The invention relates to a housing which is composed of two housing halves (1a, 1b) that form a bottom (5) and a lid (6) and an intervening section (7). According to the invention, sections of the walls of the two housing halves (1a, 1b) are configured as respective peripheral rims (10, 11) which are joined to each other while overlapping, thereby increasing the wall thickness in the area of the rims (10, 11). The rims (10, 11) thus contribute to the wall thickness required to impart to the housing the necessary stability.
