摘要

A pipe joint thrust ring (13) to be interposed between a joint member of a pipe joint and a connecting threaded member rotatably fitted to the joint member. The thrust ring (13) comprises a C-shaped body in the form of a circle partly cut away and having spring elasticity. The inner width between opposed ends of the C-shaped body is smaller than the outside diameter of the joint member and can be increased to a value equal to the outside diameter of the joint member. <IMAGE>
