A pull-tab connector capable of attaching a pull tab with a flat or round strap, simply. A connecting ring, which is adapted to be attached to a slider body, is connected to an outer side of a central frame of a U-shaped bracket of the connector. Opposite side frames of the U-shaped bracket have a pair of horizontal slots in which a strap-turning bar is slidably and rotatably received and a pair of axial holes in which a strap-insertion bar is rotatably received. The strap-insertion bar has a strap-insertion through-hole. In use, the strap is firstly threaded through the strap-insertion through-hole of the strap-insertion bar and is then turned around the strap-turning bar, and finally pulled out from the strap-insertion through-hole again. The opposite ends of the strap are pulled to be aligned with each other. Then, the strap can be attached to the connector in a simple operation and is exchangeable with another strap as desired.

Pull-tab connector for slide fastener slider

A connector-equipped cord comprises: a flat belt having on its opposite ends a number of ridges molded of thermoplastic resin; a metallic connector having a pair of jaws adapted to clamp said ends of said flat belt, said jaws having on their inner surfaces a number of teeth engageable with said ridges; and a connecting ring projecting from one end of said connector remotely from said jaws.

Connector-equipped cord

In a cord equipped with a connector, a metal or synthetic resin tube has at one end a connecting ring and in its wall a through-hole communicating with a hollow of the tube. End portions of a cord are inserted in a trued-up form in the hollow from an opening of the connector. The hollow and the through-hole are filled with a molded core insertion-molded of synthetic resin so that the molded core is prevented from accidental removal from the hollow, thus firmly holding the end portions of the cord. This connector-equipped cord is particularly useful when applied to a pull string of a second bag or a slider pull tab of a slide fastener.
