<p>Clip being constructed by combining a base body (1), plastic in nature, of noticeable stiffness, with the standard head (2) for coupling to the plate to be fastened, and the also standard locking boss (4) which can contract elastically, intended for coupling into the hole in the sheet or plate acting as support, and a collar (8) preferentially of rubber or similar material, serving as sealing element, formed between head (2) and locking boss (4), having the special characteristic that the base body (1) includes in the outside part of its head (2) an axial access (9) with channels (10) which are elbowed outwards and open into a perimetric neck (7) made in the section where the collar (8) is formed, all of the foregoing being such that first the base body (1) is injected into the mould corresponding and, afterwards, the collar is obtained in an over-moulding operation, in a second mould in which the previously obtained base body (1) participates. <IMAGE></p> |
