<p>Removable ball joint, comprising, on the one hand, a spherical ball integral with a journal and, on the other hand, a cage (3) having a cavity adapted so as to receive the ball with a certain play, the cavity being connected to the outside by a channel in order to permit the insertion of the ball, the said cage being provided moreover with means for fastening to a support, and comprising a hole (28) for self-tapping, forming part of the said means for fastening to a support and having longitudinal grooves (29) separated by ribs (30). The joint preferably comprises an electric socket (8) having at least one tab (31) threaded into a groove (29) in such a way that, during the self-tapping, a male threaded piece which bites into the ribs (30) separating the grooves (29) also bites into the tab (31) in order to ensure satisfactory electrical contact between the socket and the threaded piece. The ball cage (3) advantageously has, at its fastening end, a throat (34) and a shoulder (35) which serve as a housing and an abuttment for a piece (36) which can be cold- or hot-deformed, for sealing or protecting the connection of the joint to the support. <IMAGE></p> |
