<p>A zipper has a pair of independently movable sliders, each of the sliders having a pull. The pulls have apertures through which U-shaped projections from the sliders extend, in order to loosely pivotally capture the pulls. The apertures of the pulls are elongated, so that the aperture may fit over the U-shaped projection of the other slider. Locking holes are provided extending through the U-shaped projections. The apertures of the pulls have unbroken edges, to maintain the strength of the pulls.</p> |
