It comprises a percussion member (4) housed movably and held in a support (1), as well as a helical tensioning spring (7), one end (8) of which is fixed to the percussion member. The other end (9) of the spring (7) is held by a fastening member (10) allowing the spring to be held in a tensioned state and to release it suddenly in order to cause, by the contraction of the spring, the percussion for triggering the initiation of an explosive charge. The device is used for cutting cables, for example on boats, in the event of the loss of a mast. <IMAGE>
