ABSTRACT:
A pipe coupling includes a retainer having spring fingers that extend inwardly of the inner periphery of the coupling, 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.
