An electro-pyrotechnical igniter includes a metal case, a cap and a plastic overmolding. The metal case contains pyrotechnical material and includes at least one vent on a side wall thereof. The cap is made from electrically insulating material and covers the metal case at least at the at least one vent. The plastic overmolding covers at least one end of the cap. The metal case includes at least one shoulder arranged between the side vent and a zone of the metal case across from the end of the cap covered by the overmolding.

A metal fixing material leadthrough for igniters of airbags and/or belt tighteners includes at least one metal pin fused into a glass or glass-ceramic fixing material in a through-opening of a main body. The metal is present in a post-heated state, with an interface between the fixing material and the metal pin and an additional interface between the fixing material and an inner surface of the through-opening. The at least one metal pin, at least in its core region, consists of stainless steel, such as a chromium-containing stainless steel, the stainless steel having a thermal expansion coefficient.

A metal fixing material leadthrough for an igniter of airbags and/or belt tensioners includes a main body having a through-opening formed therein and at least one metal pin fused into a glass or glass-ceramic fixing material in the through-opening and having a core region. The at least one metal pin, at least in its core region, consists of ferritic stainless steel made to the EN 10020 standard. The ferritic stainless steel is selected in such a way that, when converted to a standard dimensioning of a metal pin diameter of 1.000.03 mm and a metal pin length of 11.680.02 mm, the at least one metal pin has a maximum elastic deflection W.sub.max of less than 0.24 mm.
