According to the invention, in order to be able to design a gas generator, in particular, for belt tighteners, with a slim housing (1), the electrical coupling is brought about via connection wires (4), pins or cables (4a) which are introduced into the housing (1) via a stopper (5) and are sealed by the latter. The stopper (5) is surrounded sealingly by the housing (1) itself or a holder element (6) sealingly connected to the housing.
