ABSTRACT:
Disclosed is a clamp for repairing a pipe. The clamp includes a flexible metal band which is held about the pipe by a pair of lugs. One of the lugs is immovably connected to the end of the band and the other lug is adjustably connected so that the length of the band between the lugs may be varied so as to accommodate different outside diameter pipes. An elastomeric gasket sheet is attached to the metal band at its central portion and includes two free ends. The gasket sheet is long enough to encircle the pipe with one of its free ends overlapping the other. The overlapping free end includes a metal strip which underlies the lugs. The gasket sheet is preferably wider than the metal band and has one edge which extends outwardly of the metal band. The outwardly extending edge is reduced in thickness and is adapted to cooperate with a channel formed in the edge of the gasket sheet of an adjacent pipe prepared clamp so that multiple clamps may be stacked lengthwise together.
