<p>A hook (2) for attaching a sheet material to a mould-formed body includes two base plates (20, 20′), a first protrusion (3) and a second protrusion (3′) protruding projectingly from the base plates (20, 20′) so that the end tips (32, 32′) of the protrusions are situated at a certain distance from each other, to engender an entry aperture (40) which leads to an anchoring seat (4) adapted to anchor an attachment element (9; 109; 209), and a bridge (21) joined to the base of the protrusions (3, 3′), so as to form a seat (23) between the edges (22, 22′) of the base plates. The seat (23) can be engaged by a tubular element (5) so as to cause the protrusions (3, 3′) to draw together to close the entry aperture (40) between the tips (32, 32′) of the protrusions.</p> |
