Casing for pyrotechnics which comprises, obtained in the same moulding operation, a conduit which defines a housing for receiving the charge and/or ignition fuse which propagates the fire to the inside of the casing via a rapid-combustion fuse. Provision has been made for the conduit to incorporate, at a preset distance from its inlet opening, a transverse element for limiting the penetration of the charge, which includes on its surface or in the vicinity thereof a plurality of passages between which are passed the ends of the rapid-combustion fuse which is secured to said limiting element by means of the pressure exerted by the charge and/or ignition fuse incorporated forcibly in the housing of the conduit. <IMAGE>
