A conduit coupling comprises a male conduit, a mating female member. The male conduit is constrained as part of the conduit leading to the coupling. The male conduit includes a member for limiting the movement of the male conduit within the female member, means for sealing, and a retainer to couple the male conduit to the female member. The female member is defined as an open port, and it is possible to be no more in diameter and depth than a screw-in connection. The connection may be a quick-connect type (in which case a tool is required for disconnection) or a non-quick-connect type (in which case a tool is required for connection and disconnection). The male conduit may either be composed of a substantially non-elastic material such as a metal or a plastic or a substantially elastic material such as a soft plastic or a hard rubber. If composed of an elastic material, the bulged area is formed by use of a rigid liner having a formed bulged area that is inserted into the elastic conduit. Regardless of its material composition, the design of the present invention allows for rotational movement of the male conduit within the female member while restricting axial translation of the conduit within the member.
