Abstract
A clamping band for clamping a resilient gasket against an opening within a wall to provide a fluid-tight seal therebetween. The clamping band is generally circular-shaped and has an elongated slot extending inwardly from one free end of the clamping band and cooperates with an elongated projection of reduced cross section as compared with the nominal cross section of the clamping band and which is provided at the opposite end of the band. The projection is inserted into the slot, the clamping band is placed against the gasket arranged within the aforesaid opening and the gasket is expanded a predetermined amount by an hydraulic expander to exert the desired clamping pressure upon the resilient gasket. One surface of the projection is provided with a series of teeth. An opening communicating with said slot receives a wedge fitted into said opening and having several teeth along one surface thereof, which teeth conform to the teeth of said projection. Insertion of the wedge inter-engages the teeth of the projection and the wedge locking the clamping band in the desired position with the requisite amount of the clamping pressure. The wedge is preferably tapped into the locking positi…
