Abstract
A ball joint comprises a ball stud containing a ball at the leading end thereof, a socket incorporating therein a receptacle for admitting of the ball, and a resilient metallic ring containing a cut therein and adapted to retain the ball rotatably within the receptacle. The receptacle is formed of a main body and an auxiliary body adapted to be attached fast to the main body, and at least the main body is formed of a plastic material. Retention of the ball within the socket is accomplished by setting the resilient metallic ring in position within the receptacle before attachment of the auxiliary body to the main body, driving the ball into the receptacle thereby causing the equator of the ball to widen the cut in the resilient metallic ring and slide past the ring, and consequently enabling the ring to get hold of the ball.
