Abstract
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.
