Abstract
A pipe coupling includes tubular body and a retainer having a continuous strap-like base band and a plurality of spring fingers that extend inwardly therefrom into the inner periphery of the body, and which are cammed outwardly by a pipe when inserted into the coupling, the spring fingers then returning to their original position under the stored spring force for them to snap into a groove in the pipe exterior, and thus provide a positive stop preventing withdrawal of the pipe axially of the coupling. The spring fingers have a generally frusto-conical configuration. In an improved embodiment, the retainer is configured as a single continuous strap-like member having a generally rhomboidal cross-sectional configuration at substantially all cross-sections therearound, and is devoid of the spring fingers and base retainer portion disclosed in the previous embodiments.
