To prevent the violent bursting of the casing of a thruster containing propergol during an accidental fire in its vicinity, a pyrotechnic composition (5, 6) is attached to this casing. This pyrotechnic composition locally heats the casing during this fire, and therefore embrittles this casing which opens at this place before the internal pressure becomes excessive. This prevents the fragmentation of the casing and the bursting out of the fragments.
