ABSTRACT:
A closure and locking device for a pipe coupling includes lugs on the juxtaposed ends of coupling segments that interfit and can be locked in a closed position by a locking pin. The lugs each provide reaction members which are employed in the pressure loading and closing of the coupling against the bias of a resilient sealing gasket contained within the segments of the coupling, with the closing accomplished with the aid of a tool which is removably engagable with the lugs of the coupling.
