The coupling includes a bolt body (12) and two radially expandable internally conical shells (16, 16'), for the externally conical sectors of the bolt. The coupling is set by wedging the shells in the intermediate space between the adjacent bolt sector (12',12") and the surrounding wall of the fixing hole. The end sector of a second part can turn about the coupling axis (12A) round the central axial sector (12B) of the bolt. Each internally conical shell has a flange (18, 18') directed radially outwards, with at least one straight flat circumferential sector (22'). The shells remain rotationally set in the use-position on a flat surface (52a,52a') on, preferably the fork arm of each fork shaped section-fixed locking piece (52,52'). |
