As long as the ignition means have not been activated, the casing is maintained firmly attached to a closing plug only by a first set of locking means so that at pressures within the casing in excess of a given pressure, the plug is ejected from the casing. As soon as the ignition means have been activated, the casing is maintained firmly attached to the plug by a second set of locking means at pressures within the casing in excess of the given pressure.
