A ball and socket joint, particularly a track rod joint for motor vehicles comprises a casing, a ball stud with a spherical head, and a socket received in the casing and being made of a material having a limited elasticity. At a flat polar surface of the spherical head, the socket is provided with an annular area which applies under biasing load against the flat polar surface and, upon an angular displacement of the ball stud, produces a restoring torque.
