<p>The module (20) has a tubular enclosure (22) made of fabric material for receiving air bag (24). An air bag outlet flap (28) is fitted in to an opening (12) of an instrument panel (10). The flap is positioned with respect to the enclosure in a spreading device of the air bag. The flap is connected to the enclosure such that compressive forces, which are effected due to spreading of air bags to the outlet flap during activation of the module, are transmitted as traction forces to the enclosure. The flap comprises a clip made of thermoplastic material.</p>
