ABSTRACT:
A clamp for securing together in locked relationship a pair of telescoped pipes or tubes. The clamp consists of a novel U-bolt having a small radius portion, two outwardly diverging tapered sections and two parallel threaded arms, and a novel saddle member having a semicircular cut-out and being further chamfered adjacent the ends of the semicircular cut-out to define a greater diameter. The assembly when in its loading position will accept a pipe joint of greater outside diameter than the inner diameter of the tightened clamp; and wherein tightening of the clamp initially deforms the pipe joint into an ovaled configuration and impresses a bead thereabout for 360.degree..
