Abstract: A suction fitting for a spa bath or pool comprising a pipe member with an externally threaded sleeve adapted to extend through an aperture in the wall of the bath or pool, a connector having a flange with a rearwardly extending internally threaded sleeve that screws onto the externally threaded sleeve of the pipe member to extend through and engage the aperture and hold the fitting against the wall, and a cover that is secured to the connector.

Abstract: A fluid coupling 10 comprising a length of flexible tubing 11 having a free end 12, a connector 13 having at least one end with at least one radially projecting rib, the end being adapted to be a force fit within the free end of the tubing so that the rib causes a radially outward expansion of the tubing, and a locking ring 30 having an inextensive band 31 coupled to resilient gripping means, the locking ring 30 being adapted to be a sliding fit on the tubing but an interference fit on the expanded portion of the tubing to cause the gripping means to engage and grip against the tubing to prevent axial separation of the tubing from the connector 13.
