ABSTRACT:
A device is disclosed for coupling a drainpipe to a recreational vehicle discharge pipe fitting of the type having a terminal end portion with circular periphery and a plurality of locking pins extending outward radially from the periphery. The device employs a tubular member having a proximal end and a distal end. A drainpipe end portion of the tubular member terminating at the distal end has a complementary shape and size adapted to engage threadably an end of a corrugated drainpipe, while a fitting end portion of the tubular member terminating at the proximal end has a complementary shape and size adapted to engage telescopically a terminal end portion of the discharge pipe fitting. Open elongated slots in the fitting end portion receive the locking pins as the fitting end portion is placed over the terminal end portion of the discharge pipe fitting and rotated about its axis, each slot extending circumferentially toward the distal end of the tubular member from an open end portion of the slot at the proximal end to a closed end portion of the slot set back from the proximal end. Elongated portions of the fitting end portion disposed between the proximal end and respective ones of the slots engage respective ones of the locking pins, and a detent in each elongated portion receives the locking pin in locking engagement.
