7. Clearance compensation unit according to claim 1 , wherein the clearance compensation spring is configured to be approximately U-shaped in cross-section comprising a base wall and two side walls, and the base wall is formed as a leaf spring or is made up of two interconnected spring shackles, and the base wall comprises a locking recess with which the clearance compensation spring is mounted on a projection of a wall in the counter connector, and the two side walls of the clearance compensation spring are formed as inwardly curved leaf springs, at least in part.

8. Clearance compensation unit according to claim 1 , wherein a side wall of the clearance compensation spring has a spring shackle which is preferably cut or punched out of said side wall, in such a way that the plug connector can be pushed counter to the insertion direction thereof, in which it can be inserted into the counter connector, by the spring shackle, it preferably being possible to push a locking means of the plug connector against a locking means of the counter connector.

9. Clearance compensation unit according to claim 1 , wherein the clearance compensation spring comprises at least one insertion tongue, which projects outwards away from the clearance compensation spring, for simple insertion of the plug connector into the counter connector, the insertion tongue preferably being provided on a front end face of the clearance compensation spring in such a way that it projects laterally outwards from a side wall, and the two side walls preferably each comprising an insertion tongue, in particular in the centre thereof.

10. Plug connector; counter connector; in particular a plug, built-in plug, coupling or socket; a housing therefor; or a support collar; preferably for an electrical RJ plug connection, comprising a clearance compensation unit according to claim 1 .

11. Clearance compensation unit according to claim 1 , wherein the axes include horizontal, vertical and axial.

12. Clearance compensation unit for a plug connection in particular an electrical RJ plug connection, comprising a plug connector and a counter connector, wherein the clearance compensation unit comprises a clearance compensation spring which has at least two spring portions in such a way that clearance between the plug connector and the counter connector can be compensated in at least two dimensions by means of the spring portions, it being possible to push the plug connector against another spring portion of the clearance compensation spring or against a limit stop of the counter connector, wherein the clearance compensation spring is configured to be approximately U-shaped in cross-section, and a base wall of the U-shaped clearance compensation spring comprises a first spring, and two side walls of the U-shaped clearance compensation spring are formed as second springs.

13. Clearance compensation unit according to claim 12 , wherein the two side walls of the U-shaped clearance compensation spring base wall are formed at least in part as inwardly curved leaf springs.
