<p>A description is given of a waterproof zip (1) comprising two rows of teeth (2, 3) attached to two tapes (4, 5) of plastic material, and a slider (6) that joins and separates the said two rows of teeth (2, 3), in which zip those zones (Z>1<, Z>2<) of the said tapes (4, 5) which lie beyond that end (1t) of the zip (1) which corresponds to the final position of the closing movement of the slider (6) form a single piece, or are hermetically welded together, and the said slider (6) is made up of at least a first part (6m) and a second part (6n) connected to each other so that they can move with respect to each other so that they can move with respect to each other at right angles to the plane ( beta ) of the zip (1), without being able to rotate, due to the action of means (7) fixed to the slider (6) itself, which movement of the two parts (6m, 6n) clamps together the two adjoining regions (4e, 5e) of the said tapes (4, 5) in their zones (Z>3<, Z>4<) adjacent to the said end (1t) of the zip (1).</p> |
