Abstract
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.
