Scalable Support for Multi-homed Multi-provider Connectivity

An improved coupling ring is disclosed having unitary structure providing spring biased engagement between cooperating members. The coupling ring has a substantially cylindrical profile including, at one end, a rigid portion with inwardly directed helical latching grooves and, at the opposite end, an integral spring portion terminating with an inwardly directed annular flange. The members to be coupled are assembled with the coupling ring engaging a shoulder of one member by the flange and with the grooves receiving lugs fixed on the opposite member so that rotation of the ring will draw the members together and hold them together in a spring loaded condition.
