ABSTRACT:
A coupling for flexible conduit of irregular configuration having an inner member adapted to be at least partially received within the flexible conduit. The inner member has a first conical surface. A locking member is retained on the inner member and is provided with a second conical surface which tapers radially inwardly and terminates in substantially a knife edge. When the inner member is received within the flexible conduit, the locking member may be moved such that the flexible conduit is squeezed between the knife edge and the first conical surface to seal the coupling to the conduit.
