Buoy (3) incorporates a release mechanism (5) that permits buoy (3) to be submersed and subsequently automatically released to ascend to the surface. Mechanism (5) includes cap (16) which hermetically seals a space (8) within which release unit (101) is located. Cap (16) is unitarily formed to include two jaws (28, 29) which are moveable relative to one another to release a pin (20). Movement of jaws (28, 29) is via release unit (101) acting to bias at least one jaw (28) away from the other jaw (29). Release unit (101) may be operated by a remotely transmitted signal, or initiated directly by a timer or a controller where specific circumstances dictate such a release (for example, the internal power source is near deplection). Buoy (3) can be attached to any submerged structure such as crab pot (7).

[ What is claimed is:] [1.]1. A releasable retaining apparatus comprising:(i) a body having at least two jaws, the jaws being configured to releasably retain a member;(ii) displacing means separated from said member by a hermetic seal formed on said body to confine said displacing means substantially within said body, said displacing means being operable to move at least one of said jaws to release or retain said member;wherein at least one jaw forms at least a part of said hermetic seal.
