Abstract

Plastic housings that are subjected to internal pressure and comprise a housing upper part, a housing lower part and a closure which connects both parts to one another. At the connecting point, the housing upper and lower part have a plurality of comb-like retaining columns shaped in a complementary manner with respect to one another such that the housing parts can be plugged together. The retaining columns are oriented in a direction in which tensile force between the housing upper part and the housing lower part is oriented when the housing is subjected to internal pressure. Retaining grooves which are oriented transversely to the effective direction of the tensile force are formed in two opposite surfaces of the retaining columns in each case. Retaining bodies which at least partially touch the areas formed by the retaining grooves and thus establish the connection can be introduced into the retaining grooves.
