A housing () which has a first part () with a first wall () having an outer wall surface () and a second part () with a second wall () having an inner wall surface (). The wall surfaces can have for example a cylindrical casing shape at least in some sections. Portions of the first wall () and the second wall () overlap in an overlap region (). The first wall () and the second wall () are connected along the circumference of the wall surfaces () by means of a rotational friction welding seam () arranged in the overlap region (). The rotational friction welding seam () has a compact zone () with a first elastic modulus and a mixing zone () with a different second elastic modulus.

The invention relates to an assembly () of a cable-connecting device () and a multi-core cable (), which form a mechanical, explosion-proof connection to each other. For this purpose, the cable-connecting device () has a plastically deformable outer sleeve () having a crimping section (). A hollow cylindrical inner sleeve () made of elastically deformable material is arranged between a cable sheath () made of elastomer and the crimping section (). An elastic deformation of the inner sleeve () and of the cable sheath () is caused by radially plastically deforming the crimping section (). Any gaps () present within the cable sheath () are closed due to the radial forces in the crimping section () such that spark-gap-free contact between the cable sheath () and the cores () of the cable () and between the cable sheath () and the inner sleeve () is ensured.
