In order to fasten a generally cylindrical gas generator cartridge (14) in a housing block (10) of a belt tensioner drive unit, the housing block (10) is provided with a bore (12) into which the gas generator cartridge (14) is pushed. A sleeve (18) is pushed onto the outer end (14a), provided with an electric igniter of the gas generator cartridge, which sleeve exhibits, at its outer end a radially inwardly directed flange (20) which engages over the end surface of the gas generator cartridge (14). At its opposite axial end, the sleeve (20) is provided with radially outwardly directed mouldings (22) which can be introduced through axial guide ducts (12a, 12b) in the bore (12) and, when the sleeve (18) is rotated in a predetermined direction of rotation, engage into a groove (20) which runs in the circumferential direction of the bore and into which the guide ducts (12a, 12b) open. <IMAGE> |
