A clamp assembly for sealing a leaking pipe weld or pipe flange joints. The clamp comprises a collar having hinged-together arcuate segments. The collar is further provided with flanges adapted to be bolted together to connect the hinged segments which may be hinged together to form a pair of semi-circular sections. Each of the segments is provided with a main annular groove on the interior circumference with means on the exterior for filling the groove with a fluid sealant under pressure. A pair of annular border grooves spaced from the main groove are provided on the opposite sides of the main groove. Additional groove means are provided in the end walls of each of the segments which connect the main groove and the border grooves to provide a sealing means between the opposed end walls when butted together.
