ABSTRACT:
An angle joint or swivel joint, consisting principally of a ball and socket wherein the ball socket is constructed preferably of a tough plastic. The ball socket has a body which is bifurcated by a central slot, thereby permitting elastic yielding of the two constituent jaws when the spherical end of the ball pin is emplaced in the ball socket. In order to prevent subsequent relative movement of the two parts of the ball socket, the body of the ball socket has a transverse profiled channel which receives a mating locking bolt having the same profile. When the locking bolt has been driven home, the two previously yielding jaws are prevented from further relative motion, thereby imprisoning the ball in the socket. A cut-out in one of the jaws permits preassembly without locking and a protrusion of the locking bolt makes possible subsequent removal and disassembly.
