ABSTRACT:
The pipe coupling includes coupling means overlying and engaging pipe end retainer rings on the juxtaposed ends of two lengths of pipe to be joined. The coupling means includes a band of generally U-shaped cross section having a wide base portion and in-turned legs. A gasket is positioned so as to form a seal between the retainer rings and the band. The free ends of the band are adapted to butt together, and means are provided to secure the free ends of the band together and to tighten the coupling means about the pipe end retainer rings so as to provide a leak tight joint.
