A retractable leash device is comprised of a housing with a handle, and a leash wound around an internal reel. The reel is biased by a spring to automatically retract the leash. A momentary unidirectional lock in the housing is arranged to be normally disengaged from unidirectional teeth on the reel. When the momentary unidirectional lock is actuated, the reel is engaged by a ratchet to prevent rotation in the release direction but permit rotation in the retract direction. A toggle lock in the housing is movable between an unlocked position away from the reel, and a locked position between cogs on the reel. A geared rotation damper is engaged with a concentric gear on the reel to limit retraction speed. A clip attached to the housing may be clipped around the leash when the leash is wrapped around a fixed object.
