ABSTRACT:
A releasable fastening apparatus includes a connecting member and a housing, the housing supporting a gripping mechanism adapted to engage the connecting member. A triggering member is movable within the housing between a first position in which it constrains the gripping mechanism in locked engagement with the connecting member, and a second position in which the gripping mechanism is disengaged from the connecting member. A shaped memory alloy actuator is employed for translating the triggering member from its first to its second position, the actuator being operable to expand longitudinally when transitioned from a martensitic to an austenitic state.
