A closure for the end of a male quick disconnect fluid coupling has an innal plug that displaces the plug normally provided in the male quick disconnect coupling, and the closure also has an outer plug wall with balls that can be radially cammed inwardly by a rotatable sleeve on the closure.

A launching mechanism is provided for ejecting a small buoy from a high sd deep depth submersible. The buoy is held in place and constrained by a pair of latch levers that lock into a groove in the buoy tail piece. The latch levers are held in place by locking pins. On launch a solenoid valve is operated allowing ambient sea pressure to actuate a release system. The sea pressure retracts a release piston assembly to which the locking pins are attached. Upon withdrawal of the locking pins, the latch levers are released by the force of neg'ator ejection springs. The ejection springs accelerate an open ended cage containing the buoy through a four foot displacement. The buoy strikes a plunger actuating a muzzle plug release mechanism that permits ejection of the buoy from the launch cage.
