ABSTRACT:
A two-piece connector includes a collar having an aperture in its relatively thick end-wall which bears an internal annular groove. The skirt of the collar is adapted to be slipped over the end of a length of tubing and contains tines to graspingly engage the outer surface of the tubing. The barb portion of the connector is adapted to fit through the aperture in the end-wall to frictionally engage the lumen of the tubing. An interrupted flange at the upper portion of the barb is adapted to twistably engage the internal annular groove in the end-wall to securely lock the barb to the collar.
