ABSTRACT:
A pipe clamp for securing together the annular overlap of a pair of assembled and engaging pipes comprises a ring body snugly and concentrically overlying said pipes and contracted or swaged thereon. The ring body is mechanically interlocked with the outer pipe and the pipes are mechanically interlocked and annularly interconnected and sealed throughout 360.degree.. The method of interlocking and sealing together a pair of telescoped pipes includes assembling a ring body around the pipes at their overlap and annularly contracting or swaging the ring body onto the outer pipe. The ring body deforms both pipes forming concentric annular channels therein and a bead in the outer pipe nested within the channel of the inner pipe, the ring body being mechanically interlocked with the outer pipe.
