Abstract

The invention concerns a device for automatic opening of a safety element, in response to a rise in temperature. The safety element (8, 11) is maintained in closed position, whether directly or not, by means of a stop member (2, 14, 17) and a spacer (3) in shape-memory alloy, such that, when the temperature reaches the shape-memory alloy transition temperature, the spacer (3) recovers its initial shape and moves the stop member, thereby releasing the safety element.
