ABSTRACT:
A male coupling with movable threaded segments, consisting of a shaft, a sleeve mounted to move along the shaft, a plurality of threaded segments surrounding the shaft and mounted to move inwardly and outwardly relative to the shaft to effectively vary the outer diameter of the assembled threaded segments, the sleeve and threaded segments including surfaces adjoining each other such that movement of the sleeve in one direction causes the threaded segments to move inwardly toward the shaft, and a spring resiliently urging the threaded segments outward.
