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. The retention body is optionally integrally formed as a portion of the hydrant, placed within a cavity in the hydrant, or includes a threaded fitting removably mated with a corresponding threaded surface on the inlet end. A deactuator has a nose sized to engage the fingers to shift the fingers against their inherent bias to allow reverse pipe movement. A second retention body may be connected to the outlet end.
