Abstract
The present invention describes a zip comprising a pair of webbings (29; 38), each of which has in its side edges sequences of coupling elements or teeth (5; 12) facing with respect to their sector of joining with the webbing, each of these coupling elements (5; 12), being able to pivot around its central vertical axis thanks to a support placed between the coupling element (5; 12) and the webbing (29; 38), wherein the coupling element (5; 12) engages with the support and the latter with the webbing (29; 38), characterised in that said support consists of a cylinder (30) or of two half-cylinders (18, 19) placed in a specular manner at the opposite sides of the webbing (29).
