Patent ID: 8528678

Claim:
An integrally molded plastic part, comprising: a main body with an opening, and a door connected to the main body at one side of the opening via an integral hinge and configured to snap into a closed position closing the opening of the main body, wherein the door at each of its two sides extending away from the hinge comprises a stopping surface via which the door, in its closed position, abuts against a supporting surface of the main body located at the circumference of the opening, and a snap-in hook protruding from the respective stopping surface and comprising a retaining surface which extends away from the hinge, and which, with its rim, engages behind an edge of a flange confining the respective supporting surface, and wherein a distance between the rims of the two retaining surfaces at the two sides of the door measured in a direction parallel to the hinge as compared to a distance between the flanges confining the two supporting surfaces measured in a direction parallel to the hinge decreases with increasing distance to the hinge, whereas distances between the retaining surfaces and the stopping surfaces as compared to distances between the edges of the flanges and the supporting surfaces increase with increasing distance to the hinge.
