retainer (1) comprising at least two similarly shaped half shells (2) respectively having a straight side (4) and a clamping side (5) in an axial direction (A), wherein at least four or eight bores (3.1 to 3.8) running in an axial direction (A) are provided, uniformly distributed over a compass of the half shell (2), wherein a respective straight first clamping face (6) having a first width is arranged on two sides of the half shell (2) lying opposite each other in a radial direction, wherein, starting from the straight first clamping face (6), a length of the half shell (2) in the axial direction (A) increases in multiple steps (7) resulting in further straight clamping faces (8, 9, 10) with an increasing width, wherein a respective first round clamping face (11) having a shape comprising a radius or a shape of a parabola or hyperbola around its apex is arranged on two sides of the half shell (2) lying opposite each other in a radial direction and offset by 90° relative to the two sides with the straight clamping faces (6, 8, 9, 10). ## Claims ### Claim 1 A clamping retainer for fastening a pole, the clamping retainer comprising: at least two similarly shaped half shells respectively having a straight side and a clamping side in an axial direction, wherein at least four or eight bores running in an axial direction are provided, uniformly distributed over a compass of the half shell, wherein a respective straight first clamping face having a first width is arranged on two sides of the half shell lying opposite each other in a radial direction, wherein, starting from the straight first clamping face, a length of the half shell in the axial direction increases in multiple steps resulting in further straight clamping faces with an increasing width, wherein a respective first round clamping face having a shape comprising one of a radius, several radiuses, a parabola around its apex, and a hyperbola around its apex is arranged on two sides of the half shell lying opposite each other in a radial direction and offset by an angle about the axial direction relative to the two sides with the straight clamping faces. ### Claim 2 (depends on 1) The clamping retainer according to claim 1, comprising four similarly shaped half shells. ### Claim 3 (depends on 1) The clamping retainer according to claim 1, wherein each half shell comprises a cross section which is one of an at least nearly circular, a square and an octahedron cross section. ### Claim 4 (depends on 1) The clamping retainer according to claim 1, wherein a respective second round clamping face having a shape comprising one of a radius, several radiuses, a parabola around its apex, and a hyperbola around its apex is arranged on two pairs of respectively two sides of the half shell lying opposite each other in a radial direction and offset by an angle about the axial direction relative to the two sides with the straight clamping faces, wherein the radius of the second round clamping face is less than the radius of the first round clamping face. ### Claim 5 (depends on 1) The clamping retainer according to claim 1, wherein the bores respectively comprise one of a square fixture, a hexagon fixture, and a double hexagon fixture on the straight side for receiving a bolt head or a socket. ### Claim 6 (depends on 1) The clamping retainer according to claim 1, further comprising four threaded rods, eight nuts and four sockets having one of a square head, a hexagon head, and a double hexagon head, each socket configured for being fixed on one of the threaded rods. ### Claim 7 (depends on 6) The clamping retainer according to claim 6, wherein the sockets are screw sockets. ### Claim 8 (depends on 6) The clamping retainer according to claim 6, wherein the sockets are embossed with the threaded rods. ### Claim 9 (depends on 6) The clamping retainer according to claim 6, wherein the threaded rods are embossed on both sides of the socket arranged thereon. ### Claim 10 (depends on 6) The clamping retainer according to claim 6, wherein the nuts are configured as one of wingnuts and star handle nuts. ### Claim 11 (depends on 1) The clamping retainer according to claim 1, further comprising four screws and four nuts, a bracket having a curved section for receiving a pole and two flanges adjacent the curved section for abutting against the straight side of one of the half shells, wherein the flanges comprise bores aligned with the bores in the half shell, when the flanges of the bracket abut the straight side, wherein the curved section comprises a central bore in the axial direction, the curved section having one of a square fixture, a hexagon fixture and a double hexagon fixture for a nut or socket on its inside, wherein furthermore a bolt for screwing into the central bore is provided. ### Claim 12 (depends on 11) The clamping retainer according to claim 11, wherein two pressure plates are provided for being received in the curved section of the bracket, wherein the two pressure plates comprise grooves facing each other in an assembled state for receiving the pole. ### Claim 13 (depends on 12) The clamping retainer according to claim 12, wherein mutually complementary ribs and notches for guiding the pressure plates in the axial direction are provided in the curved section and on the pressure plates. ### Claim 14 (depends on 12) The clamping retainer according to claim 12, wherein the half shell comprises a wall in the direction of the straight side, wherein the wall and a side of the pressure plate determined for abutting the wall comprise mutually complementary indentations and protrusions. ### Claim 15 (depends on 14) The clamping retainer according to claim 14, wherein a circumferential rim around the wall is provided for positioning the flanges. ### Claim 16 (depends on 14) The clamping retainer according to claim 14, wherein the wall is reinforced by reinforcing ribs inside the half shell, wherein the shape of at least one of the clamping faces is repeated on at least one of the reinforcing ribs. ### Claim 17 (depends on 16) The clamping retainer according to claim 16, wherein the reinforcing ribs comprise four reinforcing ribs respectively starting from one of the bores of the half shell and running toward a neighboring one of the bores of the half shell so that the four ribs form one of a square and a square having a pincushion distortion. ### Claim 18 (depends on 11) The clamping retainer according to claim 11, wherein the bolt for screwing into the central bore is configured as a star handle bolt. ### Claim 19 (depends on 11) The clamping retainer according to claim 11, wherein furthermore a cap is provided for fitting onto an end of the bolt located within the bracket. ### Claim 20 (depends on 1) The clamping retainer according to claim 1, wherein the half shell is shaped as a ring, which is partially hollow and open toward the clamping side in such a way that the ring, at least aloof from the bores, comprises a radially internal wall and a radially external wall, which are connected to each other around the bores and on the straight side.
