Device for sealing of holes in pieces of any type

摘要

The stopper is made from a supple or semi-rigid material. The stopper consists of a frame-shaped member (1) with flexible lugs (4). The lugs fit into a hole (6) made in a panel (P). A shutter (2) is joined to the frame by a hinge (3) and has locking lugs (5). The locking lugs press the frame's lugs against the sides of the aperture when it is folded over it and pressed. The frame and shutter are made in one piece from a moulded synthetic material. The hinge has the form of a thin section of the material between them.
