ABSTRACT:
A coupling member for building into the end portion of a hose. The coupling member includes a portion which extends into the bore of the hose body and has one or more annular protuberances extending around the exterior surface. At least one notch extending into one of the protuberances provides a seal to prevent the flow of the fluid passing through the hose from leaking between the outer surface of the coupling member and the hose bore.
