ABSTRACT:
A coupling sleeve for joining the ends of two conduits. One end is threaded, the other is unthreaded. The coupling sleeve has a female thread which engages the threaded end. The unthreaded end has a terminal portion of reduced external diameter running to an inwardly displaced groove in which a locking ring is disposed. The end of the coupling sleeve which engages the unthreaded conduit end has a recess in which the locking ring is axially slidable and a flange that engages a full diameter external section of the unthreaded end. The recess is long enough to permit the coupling sleeve to be fully received on the unthreaded conduit end when the female thread is disengaged from the threaded end of the conduit.
