A pressure vessel (10) containing fluid (18) under pressure has a first part (38) which is formed of aluminum. An igniter housing (110) comprises a tubular part (112) with a reputable end wall (122) subjected to the pressure of the fluid (18). The tubular part (112) contains an igniter (40) which, when actuated, ruptures the end wall (122). The igniter housing (110) is formed of steel, and is fixed to the first part (38) of the pressure vessel (10) by a friction weld (150). The friction weld (150) blocks the fluid (18) from leaking outward from between the igniter housing (110) and the first part (38) of the pressure vessel (10).
