6. The device as claimed in claim 2, characterized in that the circlip (13, 24) is in the form of a spring ring, a Seeger ring or an O-ring.
7. The device as claimed in claim 6, characterized in that the circlip (13, 24) has an angular, round or oval cross section.
8. The device as claimed in claim 2, characterized in that the radial depth of the circumferential groove (6, 14) in the pin (10) is less than half the radial extension of the material of the circlip (13, 24).
9. The device as claimed in claim 8, characterized in that the circlip (13, 24) can be received completely on its radially outer side, and at least partially in the axial direction, in an opening (25) of the bushing (12).
10. The device as claimed in claim 2, characterized in that the articulated body is in the form of a coupling inner part (2) or a coupling outer part of a drive coupling.
