ABSTRACT:
The invention pertains to a fitting consisting of a tubular body which may be readily installed over the end of a smooth wall conduit and removed therefrom and may be quickly connected to a standard unisex adapter mounted on the end of a hose line to place the conduit and hose line in fluid communication. The fitting includes a positive lock for attaching the fitting to the conduit and a flexible retainer is employed for safety purposes to resist "blow off".
