The invention relates to a plastic enclosure (1), which comprises a base section (3) and a lid section (4) which form, the enclosure being closed, a base (33) and a lid (43) of the enclosure, and walls (45, 35) remaining between said lid (43) and base (33), whereby on an inner surface (33a, 43a) of the enclosure base (33) or lid (43) or an inner surface of a joining section (7) used for the mutual joining of the enclosure (1) base section (3) and lid section (4) abuts at least one sleeve-like array (2) protruding from the plane of the inner surface/inner surfaces in question at an angle of about 90 degrees which is arranged to receive a fastening element with an external thread (6). From an inner surface (2a) of the sleeve-like array (2) protrudes in the direction of a radius (2r) of the sleeve-like array (2) a set of elongated grooves (200) in the longitudinal direction of the sleeve-like section. |
