ABSTRACT:
In a plastic housing of the "Flameproof Enclosure" ignition protection type, one part of the housing is provided at the parting plane with a rib (31) and the other housing part is provided with a groove complementary thereto. The cross-sectional dimensions of the groove are larger than the cross-sectional dimensions of the rib (31). The gap-like space obtained thereby is filled with a coating which adheres integrally either to the rib (31) or to the walls (14, 15) of the groove (13). This gives rise, between the coating and the other part to which it does not adhere integrally, to a gap which meets the requirement placed on an "ex-gap" of a flameproof housing.
