Abstract: A detonator is intended to be installed in a chamber equipped with a blockable access opening. The detonator includes a member for initiating a pyrotechnic chain and a casing for confining the initiation member. The casing includes, facing the initiation member, a port for igniting a pyrotechnic charge placed in the chamber outside the casing. The detonator also includes a shutter for blocking the port which can be moved between a retracted position clear of the port and a position for blocking the port. A device for operating the shutter keeps the shutter in the retracted position when access to the chamber is blocked, and in the blocking position when access to the chamber is open.

Abstract: The invention concerns a device for altering the appearance of valuable articles comprising at least a reservoir (22) filled with a fluid adapted to soil said articles and a pyrotechnic charge (24) associated with said reservoir (22) for opening the latter to release said fluid on said articles. The (each) reservoir (22) is substantially defined by a wall made of a fragmentation material adapted, by the effect of the pyrotechnic charge (24), to produce a multitude of scattered elementary splinters. The invention is applicable to suitcases for the transport of funds.
