The cartridge has a casing (1) and a series of charges (2) traversed by an ignition cord (16). Between the combustible charges and the end wall (6) of the casing, there is a spacer (7) which defines a chamber between the end wall and the closest charge. In this chamber, and also in the chamber delimited by the cover (3), once combustion of the charges has been initiated, the combustion gases are progressively stored until sufficient pressure is achieved to cause detachment of the cover and expulsion of the charges outside the casing. The cartridge comprises a casing housing a series of charges (2) of combustible, smoke-generating, tear-generating or signaling mixture, which have a coaxial passage (15) through which an ignition cord (16) passes. The casing is closed by a detachable cover (3) which delimits an internal chamber and carries a fuse (18) whose activation gives rise to ignition of the cord and thereby the ignition of the charges.
