PERFECTED ZIPPER CLOSURE, characterized essentially by the fact of being constituted by two halves completely independent of each other, upper and lower respectively, between which they continue forming, as in the known cases, a single channel bifurcated in two independent by means of which it makes the opening and closing of the zipper, but with the particularity that said two halves, independent of each other, are coupled by rotation axis located in the front part of the closure, that is, at the point where the division of the two channels, so that the relative position between both halves can be modified by moving one with respect to the other in angular movement that has as its vertex the common axis of rotation.
