An annular-shaped, expansion type clamping band has laterally overlapping ends, each having a skewed surface, the skewed surfaces slidably engaging one another. The ends are further provided with elongated guide slots for receiving a threaded bolt. A threaded nut threadly engaging the bolt, when tightened, moves the overlapping ends toward a longitudinal central axis of the band whereby the band expands to exert an outward radial force against an interior surface of a gasket to provide a liquid-tight fit between the gasket and an opening having a surface engaging an outer periphery of the gasket. The band may be a one-piece or two-or-three-piece assembly and may be formed of an suitable metallic or plastic material. The threaded member is slidable along the aforesaid guide slots enabling the bolts to be self centered. The nut and bolt assembly, in one embodiment is designed to require only one tightening tool.
