The invention relates to a housing (1) for an electrical operating means such as a light, plug-in device, measuring instrument, switch, distributor, or the like, having at least one first and one second housing part (2,3) that can be assembled with one another in an explosion-proof fashion. Each housing part has one joining surface (4,5); when the housing parts are assembled, said joining surfaces are in contact with one another, forming a penetration-proof gap (6). In order to provide a novel structure of joining surfaces by means of which a corresponding penetration-proof gap is formed independently of the cross-sectional shape of the housing parts and to be able to substantially unite the advantages of both joining surfaces and the housing mentioned above, the joining surfaces run substantially perpendicular relative to the rest of the housing parts and surface profiles (7, 8) are formed in said joining surfaces, the penetration-proof gap being formed between said surface profiles.
