A connector assembly for a heating, ventilating, air conditioning system includes a take-off pipe and a collar. The take-off pipe is cylindrical in shape and has a number or outwardly extending resilient tabs and grooved outer wall segments. The collar is cylindrically sized to mate with the take-off pipe, and has a number of protrusions extending from an inner wall. The take-off pipe is first inserted into an opening in a main duct, with the resilient tabs retaining the take-off pipe in place. The collar slides over the body with the protrusions engaging one of the grooves of the wall segments to retain the collar in place. Rotation of the collar disengages the protrusions from the grooves for collar removal.
