ABSTRACT:
A quick change PVC pipe connection system (10) comprises a pipe (12) having a pair of opposite spaced apertures (14) extending through one end (16). A fitting (18) has a flange (20) with a pair of opposite spaced orifices (22) extending through the flange (20). A pair of pins (24) are provided. A facility (26) within the pipe (12) is for forcing each pin (24) through one aperture (14) in the pipe (12) and into one orifice (22) in the flange (20) of the fitting (18), when the end (16) of the pipe (12) is inserted into the flange (20) of the fitting (18), so as to retain the pipe (12) to the fitting (18).
