A release comprises cylindrical first and second connectors having supply passages, one of which is mounted on the supply tube and the other of which is mounted on the mask. The first connector has a cylindrical chamber for receiving a cylindrical portion of the second connector to connect the connectors and operatively connect the tube to the mask to enable supply of breathing gas to the mask. The second connector has a groove formed in its outer surface for receiving a split spring ring carried by the first connector. The free ends of the arms of the split ring have cam surfaces. A spring is mounted on the second connector and is compressed by insertion of the second connector. An unlocking device comprises an electrically-actuated explosive device carried within the first connector and a wedge which is projected against the cam surfaces upon actuation to force the spring arms apart, to force the split ring out of the groove. This unlocks the couplings which are forced apart by the spring, connecting the mask wearer to ambient atmosphere through the mask supply passage.

An amphibious toy vehicle having paddles located within the wheels of the toy vehicle which can be extended outside the wheels in order to propel the vehicle forward and backward in water. A flotation chamber is provided at the bottom of the vehicle. A gear assembly including rack gears is used to extend and retract the paddles. After the paddles are retracted inside the wheels, the toy vehicle may be moved over a supporting surface by the rotating wheels. A downwardly extending portion attached to an upper body of the amphibious toy vehicle helps to keep motors mounted inside the vehicle dry when the toy vehicle is placed in water.
