ABSTRACT:
In the representative embodiment of the invention described herein, an adjustable sprinkler for a fire protection system has a sprinkler assembly tube which is mounted for longitudinal movement in a bore extending longitudinally into a component of a fluid supply piping network for the fire protection system. A latching device is resiliently urged into the bore of the component to prevent accidental removal of the sprinkler assembly tube during its longitudinal movement in the bore by releasably engaging the sprinkler assembly tube before it is completely removed from the bore. When the sprinkler assembly tube is disengaged by the latching device, the sprinkler assembly tube can be removed from the bore.
