ABSTRACT:
A pipe clamp for use in encircling a pipe or main as either a pipe repair clamp or a service side outlet clamp. The pipe clamp comprises a flexible metal band made of sheet metal or the like having a gasket liner which seals with a section of the exterior of the pipe, the band being split and made of at least one section and having at least a pair of lugs attached to each of its opposed end portions. Bolts are used to draw the lugs together and cause the band to tightly encircle the pipe. An improved retention of the band ends in the lugs is provided, the lugs being of the type having ductile jaws initially cast in an open position, one of the jaws having a projection thereon and the other jaw having a recess for cooperating with the projection when the jaws are closed on the band end. The cooperating projection and recess are dimensioned to provide a space between the same when the jaws are closed, the space having a first portion of less thickness than the metal band whereby the band is reduced in thickness when the jaws are closed and another portion with a thickness at least as great as the thickness of the band to provide for ease in closing the jaws.
