ABSTRACT:
A U-bolt clamp assembly for securing together the annular overlap of a pair of telescoped engaging pipes having a U-bolt having a semi-circular bight portion terminating in a pair of legs having threaded ends. A saddle plate assembly includes a saddle plate having a concave seat of semi-circular shape and a pair of spaced keys at the upper ends of the saddle plate seat. The saddle plate assembly is apertured at its ends to receive the U-bolt legs. Opposed keyways upon the interior of the legs interlockingly receive the keys. Fasteners upon the U-bolt ends are tightly drawn into compressive engagement drawing together the U-bolt and saddle plate assembly. The U-bolt bight and the concave seat deform both pipes forming concentric annular channels therein and a bead in the outer pipe nested within the channel of the inner pipe so that the U-bolt and saddle are mechanically interlocked with the outer pipe and the pipes are annularly interlocked, secured and sealed throughout 360.degree..
