Abstract

A ball-and-socket joint has a housing, a ball pivot (3) mounted pivotably in the housing, and a sealing bellows (1), which is fastened to the housing and is mounted on the ball pivot (3) slidably via a sealing ring (4) provided with two legs (5, 6). A first leg (5) of the two legs (5, 6) is in contact with the ball pivot (3) under tension and the second leg (6) meshes with the wall of the sealing bellows (1). The second leg (6) is, furthermore, fastened in an anchoring ring (7) arranged at least partially in the wall of the sealing bellows (1).
