A hydrant for use with a plumbing outlet pipe has a fluid passage passing from an inlet end to an outlet end and a retention body connected to the inlet end. A slip clutch adapted to contractibly receive the pipe and prevent reverse pipe movement therethrough is located within the retention body. The slip clutch comprises a retaining ring having a plurality of sloped spring fingers normally allowing pipe movement in a linkage-contracting direction but preventing reverse pipe movement.
