Abstract: A collar, slidably carried upon the barrel of a wand-type spray gun, is normally urged rearward against a stop by a compression spring. Disposed between the stop and the collar is a ring-like member which rocks relative the barrel using the edge of the collar as a fulcrum. The ring-like member abuts a lip extending radially inward from the forward end of a holder tube and prevents expulsion of the spray gun in response to the rearward force from the emission of high pressure fluid from the nozzle of the spray gun. Slight pressure upon the handle readily withdraws the spray gun from the holder and tapered fins carried by the collar. A ramp depending from the lip guides the spray gun into the holder.
