ABSTRACT:
An improved device for fastening a separable zipper includes specially adapted terminals disposed at the respective ends of opposed rows of zipper teeth and a specially adapted slider supported by one of the terminals. The slider is provided with an annular disc which can be inserted in a cooperating aperture of the other terminal by movement in a direction substantially perpendicular to the zipper rows. A second embodiment of the invention includes specially adapted terminals and two sliders, the sliders being disposed in back-to-back relationship and supported on one of the terminals, the sliders including an annular disc separable into semicircular halves for guiding the sliders into nesting engagement with the other terminal by movement in the direction substantially perpendicular to the zipper rows.
