Abstract: The invention relates to a plastic enclosure for enclosing industrial components. The enclosure comprises a case (2), a lid (9), and a latch device (13) for locking the lid to the case. The lid (9) has a grip means formed as a rigid lug (14) molded to be monolithic with the lid (9), the lug comprising a throughhole (19) to which a hook portion (17) of a rocker (15) can grip. The lug (14) is arranged, in the closed position of the lid, to extend over and at a distance from the second wall (7) to be substantially in parallel with a wall of the case to limit an intermediate space between the wall (7) and the lug (14) when the lid is in the closed position.
