The invention relates to plastic housings which can be subjected to internal pressure and comprise a housing upper part (10), a housing lower part (20) and a closure (30) which connects both parts to one another. At the connecting point, the housing upper part (10) and the housing lower part (20) have a plurality of comb-like retaining columns (11, 21) which are shaped in a complementary manner with respect to one another such that the housing parts (10, 20) can be plugged together. The retaining columns (11, 21) are oriented in the direction in which the tensile force between the housing upper part (10) and the housing lower part (20) is oriented when the housing is subjected to internal pressure. Retaining grooves (13, 23; 16, 25, 26) which are oriented transversely to the effective direction of the tensile force are formed in two opposite surfaces of the retaining columns (11, 21) in each case. Retaining bodies (32; 35, 36) which at least partially touch the areas formed by the retaining grooves (13, 23) and thus establish the connection can be introduced into the retaining grooves (13, 23). |
