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.

An expansion clamp for use with a resilient tubular gasket having radially spaced axially extending inner and outer surfaces, the outer surface of said gasket adapted to engage the inner surface of a tubular body at an opening therein, said clamp comprising: a. a circumferentially extending member Adapted to be maintained in compressive relation with said radially spaced inner surface of said tubular gasket and said inner surface of said tubular body, said member having a substantially C-shaped transverse cross-section to define a channel with the opening thereof extending radially inwardly; b. one circumferential end of said channel terminating in an end portion adapted to be received within the other circumferential end of said channel, said other circumferential end including an inwardly axially extending lip on said channel to prevent radial displacement of said one end portion; and c. means for slidably engaging and locking said one circumferential end portion within said other circumferential end in a predetermined fixed position to maintain said compressive relation, said means including a transverse aperture contained on said circumferentially extending member disposed proximate to said one end thereof and said other end terminating in a relatively flat circumferentially extending portion having at its free end a hook-shaped part adapted to engage said transverse aperture in said predetermined fixed position.
