A ball and socket joint includes a housing (11) a ball pin (17) and a resilient plastics bearing cup (14). The bearing surface of the cup is protected by a rubber seal (19) retained by radially deformable retaining means in the form of a resilient plastics retaining ring (21), the ball pin, bearing cup, seal and retaining ring being assembled together before insertion into the housing. The retaining means may comprise a groove wall (38,44) formed integrally with the bearing cup (34,41). |
