Abstract: A pull tab mounting arrangement includes a pull tab, and a coupling device coupled to a slide for a zipper to hold the pull tab, the coupling device has a substantially U-shaped spring wire rod at one end hung on a hanging hole on the slide, and a slotted bottom extension strip coupled to a split ring at one end of the pull tab, the U-shaped spring wire rod having one end pivoted to the body of the coupling device by a pivot pin, and an opposite end terminating in a retainer tip detachably forced by the spring power of the U-shaped spring wire rod into engagement with a retaining hole on the body of the coupling device.

Abstract: The structural design of an invisible zipper with an open-end, particularly indicating an innovation which employs to modify the conventional invisible zipper with closed-end into an invisible zipper with open-end, mainly consists of an open-ended chain tape, a resilient tape hook, an inserting pin and a rectangular box; The ends of the left and right open-end chain tapes are formed into rubberized fabric portions by thermal melting rubber; an inserting pin and a resilient tape hook, which are made by plastic injection molding or punching, are fixed to the left and right rubberized fabric portions of the chain tape, and after the separating chain tapes are sewed to the clothes, and the resilient tape hook set up at one of the chain tapes is forced to wedge into a rectangular box, one can make use of this kind of design to fabricate an invisible zipper with open-end.
