An angle element (22) with a spherical surface (23) at which the two ends of a through-passage (32) penetrating the angle element (22) open out serves to adjust a multitude of angles (.alpha.) between the structural component parts (1, 10), which angles (.alpha.) can be changed preferably between preselected limits. The connection ends (7, 15) are provided in the area of the joint faces (24, 25) with contact surfaces (27, 28) adapted to the spherical surface (23) so that fine, hardly visible joint faces (24, 25) are formed between the structural component parts (1, 10) and the angle element (22). A connection element (21) which penetrates the through-passage (32) and is adaptable to the preselected angle is provided for producing a fixed connection or clamping of the angle element between the two structural component parts (FIG. 1 ). ## Claims ### Claim 1 Connection system for connection of two structural component parts containing connection ends having front recesses, axes and cylindrical outer surfaces, comprising: an articulated connection element serving for connecting said structural component parts in selected ones of a plurality of possible angular positions between said axes and having connection means determined for being anchored with the structural component parts and for being inserted into the connection ends thereof; and an angle element having a spherical surface and a through-passage receiving said connection element in said plurality of angular positions, said through passage having two ends ending at said spherical surface, and said angle element being mountable between said connection ends under a formation of joint faces with said spherical surface, wherein the connection ends are provided with concave curved contact surfaces for contacting said spherical surface in such a manner that said cylindrical outer surfaces open into said spherical surface substantially tangential when said structural component parts and said angle element are connected with each other by means of said connection element. ### Claim 2 (depends on 1) Connection system according to claim 1, wherein said connection means are two pins which are connected with one another in an articulated manner. ### Claim 3 (depends on 2) Connection system according to claim 2, wherein at least one of the pins is a threaded pin. ### Claim 4 (depends on 2) Connection system according to claim 2, wherein one of said pins has a head at a free end thereof. ### Claim 5 (depends on 4) Connection system according to claim 4, wherein said head is provided with means for application of a tool. ### Claim 6 (depends on 1) Connection system according to claim 1, wherein said connection ends of the structural component parts are constructed in a cylindrical manner and wherein said spherical surface has a diameter substantially corresponding to a diameter of said connection ends. ### Claim 7 (depends on 1) Connection system according to claim 1, wherein the through-passage and the connection element are provided with means for producing a connection between said connection element and said angle element such that said connection element and said angle element are fixed with respect to rotation relative to one another. ### Claim 8 (depends on 1) Connection system according to claim 1, wherein said through-passage has ends being defined by walls which cooperate with said connection element and fix two extreme angular positions between said two structural component parts. ### Claim 9 (depends on 1) Connection system according to claim 1, wherein said angle element and said connection element are connected with one another so as to be fixed with respect to rotation relative to one another. ### Claim 10 (depends on 1) Connection system according to claim 1, wherein said angle element is constructed for continuous adjustment of a multitude of angles (.alpha.) between the structural component parts. ### Claim 11 (depends on 1) Connection system according to claim 1, wherein said angle element is constructed for adjusting an angle (.alpha.) between two preselected limits. ### Claim 12 (depends on 1) Connection system according to claim 1, where said through-passage has an elongated hole-like cross-section and wherein said connection ends are provided in a region of said contact faces with cut out portions which can cooperate with each other in a manner of a miter. ### Claim 13 (depends on 1) Connection system according to claim 1, wherein the connection elements is provided with means for producing a connection between said connection element and said angle element such that said connection element and said angle element are fixed with respect to rotation relative to each other.
