a gripping section, wherein the end section projects from the gripping section in an axial direction, wherein the pitchfork has at least one prong and is mounted on the cylindrical body by means of a slot in the cylindrical body and a pin in the pitchfork such that the pitchfork is movable axially over an outer circumferential surface of the cylindrical body and the pin is not fixed in a single position relative to the golf club, wherein the pitchfork can be fixed on the cylindrical body by means of the slot and pin in a retracted position and in an extended position, wherein, in the retracted position, the pitchfork rests against the outer circumferential surface of the cylindrical body and the spring is in a compressed state within the cylindrical body, and wherein, in the extended position, the at least one prong projects beyond the cylindrical body in the axial direction and the spring is in an elongated state within the cylindrical body; and a clamping section, wherein the clamping section can be inserted into a tubular shaft or grip of the golf club, wherein the clamping section projects from the gripping section in a direction opposite to the axial direction, wherein at least one of the clamping section or an insert on which the clamping section is provided has an essentially cylindrical shape at least in sections and comprises radially projecting clamping lugs, by means of which the clamping section can be clamped into the golf club, and wherein each of the clamping lugs has a steeper side in the axial direction than in the opposite direction. ### Claim 2 (depends on 1) The device according to claim 1, wherein the slot comprises a first detent area, an elongate connecting section and a second detent area, wherein the elongate connecting section connects the first and second detent area with each other. ### Claim 3 (depends on 2) The device according to claim 2, wherein the elongate connecting section runs in the axial direction. ### Claim 4 (depends on 1) The device according to claim 1, wherein the pitchfork can be released from at least one of (i) the retracted position by a force of the spring or (ii) the extended position against the force of the spring. ### Claim 5 (depends on 4) The device according to claim 4, wherein the cylindrical body has a cavity and the spring is received in the cavity. ### Claim 6 (depends on 1) The device according to claim 1, wherein the clamping section is formed in one piece together with the gripping section. ### Claim 7 (depends on 1) The device according to claim 1, wherein the clamping section is provided on an insert and the gripping section is provided on a gripping piece formed separately from the insert, and wherein the insert can be inserted firmly into a tubular shaft or grip of the golf club. ### Claim 8 (depends on 7) The device according to claim 7, wherein the insert and the gripping piece can be connected to each other firmly by connecting means. ### Claim 9 (depends on 8) The device according to claim 8, wherein the insert and the gripping piece can be connected to each other firmly by screwing. ### Claim 10 (depends on 1) The device according to claim 1, wherein the clamping lugs have a movement-impeding material on surfaces which project outwards in a radial direction. ### Claim 11 (depends on 1) The device according to claim 1, wherein at least one of the clamping section or an insert on which the clamping section is provided has an adhesive on its outer surface for securing onto the golf club. ### Claim 12 (depends on 1) The device according to claim 1, wherein at least one of the clamping section, an insert on which the clamping section is provided, the gripping section, the cylindrical body or the pitchfork is formed from plastic. ### Claim 13 (depends on 1) The device according to claim 1, wherein the device has a mass of between 20 and 40 grams. ### Claim 14 (depends on 1) The device according to claim 1, wherein the clamping lugs are molded onto spring shackles. ### Claim 15 (depends on 14) The device according to claim 14, wherein the spring shackles extend in the axial direction.
