ABSTRACT:
An expansion clamp for use with a resilient tubular gasket to provide a leakproof joint in a piping system including a substantially C-shaped circumferentially-extending member having end portions cooperating with one another and further including means for locking the end portions with respect to each other so as to maintain the expansion clamp, the gasket, the inner circumferential surface of the pipe in mutual compressive relation. One end of the C-shaped member is also provided with means to prevent axial and radial displacement of the other end portion.
