Abstract
A fluid fitting coupling system which retains two assemblies axially through the use of a flange and lip arrangement and simultaneously retains those assemblies rotationally through either a radial detent or a snap spring are shown in variations. The designs are especially configured for molding so that each might utilize the material properties available and yet be economically manufactured. Further, user features including both visual and potentially audible indications of full assembly are incorporated into the designs and automatically achieved. Shut-off valve designs are shown which are automatically delayed in opening until some axial retention occurs to minimize any blow-off or other undesirable operational events. Swivel features may be incorporated when the application requires.
