The invention relates to a pyrotechnic generator of hot gases (1) and to a process for its manufacture. The generator is in the form of a cylindrical tube (2) which comprises a side wall (3) the length (L) of the generatrices of which is at least two times greater than its external diameter (D), the said tube (2) being made up of two parts, an upstream part (4) including especially an ignition system and a pyrotechnic charge (14), and a downstream part (5) forming a diffuser (22). The process of manufacture consists in inserting and fixing a nozzle (17) into the tube (2) and then successively introducing a filtering grid (16), an enclosure (12), a wedging ring (11), the ignition system and a leakproof plug (21). The invention makes it possible to produce a generator intended to inflate a cushion for protecting the occupants of a motor vehicle.
