A resilient retention method 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.

1. A method of coupling fluid fitting assemblies together comprising the steps of: a. axially engaging a first fluid fitting assembly having a first fluid fitting body, a central axis, and a first fluid passageway and a second fluid fitting assembly having a second fluid fitting body, a central axis, and a second fluid passageway; b. compressing a spring member disposed between said first and second fluid fitting assemblies; c. rotating said first fluid fitting body with respect to said second fluid fitting body; d. axially retaining said first fluid fitting assembly with respect to said second fluid fitting assembly; e. decompressing said spring member; and f. rotationally retaining said first fluid fitting body with respect to said second fluid fitting body through action of said spring member wherein said step of rotating said first fluid fitting body starts after the start of said step of compressing said spring member. 2. A method of coupling fluid fitting assemblies together as described in claim 1 wherein said step of compressing said spring member comprises the step of axially compressing said spring member. 3. A method of coupling fluid fitting assemblies together as described in claim 2 and further comprising the step of completely relaxing said spring member. 4. A method of coupling fluid fitting assemblies together as described in claim 2 wherein said step of axially engaging said first fluid fitting assembly and said second fluid fitting assembly comprises the step of inserting a flange into a flange recess and wherein said step of rotationally retaining said first fluid fitting body with respect to said second fluid fitting body comprises the step of inserting a restraining tab into said flange recess. 5. A method of coupling fluid fitting assemblies together as described in claim 1 further comprising the steps of: a. freely allowing rotation of a stem with respect to at least one of said fluid fitting assemblies when accomplishing said step of rotating said first fluid fitting body with respect to said second fluid fitting body; b. axially retaining said stem with respect to the fluid fitting body surrounding it; and c. sealing said stem to said other fluid fitting assembly. 6. A method of coupling fluid fitting assemblies together as described in claim 5 further comprising establishing a pair of generally semi-circular body halves around said stem. 7. A method of coupling fluid fitting assemblies together as described in claim 6 wherein said axially retaining said stem with respect to the fluid fitting body surrounding it further comprises rotatably engaging said pair of generally semi-circular body halves around said stem with said stem retaining element.
