Housing for receiving electrical and / or electronic internals

The invention relates to a housing for receiving electrical and / or electronic internals having two mutually spaced-apart covers the extending means vertically to the covers, mutually parallel profile arms are connected, wherein at least one of the vertical to the covers extending sides of the housing at least by means of a side wall is partially covered, and wherein the side wall has at least one in direction towards the cover bent edge that overlaps a flange of the cover. To be able to quickly and easily perform the connection of the side walls in such a case, it is inventively provided that the flange of the cover has one or more openings which are arranged in alignment with openings of the edge of the side wall, and in that aligned in mutually breakthroughs engages a projection of a connecting element, which applies at least in partial regions of its periphery to the inner contour of the apertures.
