Improved zipper closure, characterized in that it comprises a longitudinal flexible plastic strip, obtained by extrusion, in the process of which longitudinal ribs are provided on both sides and close to their edges; these have two cylindrical recesses or recesses provided with a groove of rectangular section coplanar with the band and of the same thickness; said band is divided longitudinally by die-cutting into two equal halves, while at the same time that are produced in the cylindrical ridges equidistant spherical teeth, thus forming the two longitudinal parts of the rack, which face their teeth alternately so that by means of a running piece of close, guided by the longitudinal ribs, determine the closure or opening of the zipper.
