Abstract
A snorkel with a unique strap hook and snorkel tube arrangement which permits both selective release and adjustment of the strap hook, but only when release or adjustment is desired and not by inadvertence. In a preferred embodiment, the snorkel tube is provided with a hook slide region enclosed along the tube surface by an elongated border. Inside each side of the border there is a recess for receiving rails of a strap hook having dove tail cross-section rails. The dove tail relationship between the recesses and the rails prevents inadvertent release of the strap hook from the snorkel tube. However, an opening at one end of each such recess, permits selective removal of the strap hook from the snorkel tube. Selective adjustment of the position of the strap hook is controlled by a plurality of teeth along the center of the hook slide region and a semi-flexible catch on the strap hook which nominally engages the teeth so that only when the catch is lifted off of the teeth can the strap hook be re-located along the snorkel tube.
