ABSTRACT:
An assembly for joining a section of pipe to a pipe fitting in which the pipe may be inserted into the fitting. The open face of the fitting has several J-shaped locks around its periphery into which locking lugs on a locking clamp may be inserted. The locking clamp includes a first and second locking clamp element each one being an annular one-half ring with a prong at one end and a cavity at the other to form a ring. The locking lug is on each such element and is adapted to fit into the J-shaped lock on the pipe fitting. The inner surface of the annular ring is provided with blades for embedment into the outside wall of the pipe as the two half rings are pulled together by tightening the bolts.
