Abstract
A retention and triggering mechanism with a shape memory actuator which ensures safe triggering and is of simple design and requires little energy. An end (7, 8) of a stressed wire is held by a free end of a wire made of shape memory material (9, 10) which contracts along its length when heated, thus withdrawing its free end from an opening (27, 28) formed in the end (7, 8) of the stressed wire thereby releasing the stressed wire.
