A COUPLING NUT (2) CAPTIVELY MOUNTED ABOUT THE BODY (1) OF THE COUPLING WITH SLIDING MOVEMENT ALONG THE BODY (1) OF THE COUPLING AND HAS A SCREW THREADED INTERIOR (7). THE TUBULAR TAIL (3) EXTENDS AT LEAST PARTIALLY THROUGH THE INTERIOR OF THE COUPLING NUT (2) SUCH THAT WHEN THE END OF A PIPE (5) HAS BEEN PUSHED PARTLY ONTO THE TUBULAR TAIL (3) THE COUPLING NUT (2) MAY BE MOVED ALONG THE BODY (1) OF THE COUPLING TOWARDS THE TUBULAR TAIL (3) TO THREADEDLY ENGAGE THE NUT (2) ONTO THE EXTERIOR OF THE PIPE END. THE COUPLING NUT (2) MAY BE ROTATED TO DRAW THE PIPE (5) FURTHER ONTO THE TUBULAR TAIL (3) OF THE COUPLING AND CLAMP THE PIPE END BETWEEN THE THREADED INTERIOR (7) OF THE COUPLING NUT (2) AND THE EXTERIOR OF THE TUBULAR TAIL (3) OF THE COUPLING EXTENDING WITHIN THE PIPE END.(FIG. 2)
