A slide fastener slider has body and diamond preferably of molded plastic parts. The parts are held together in snapfastener fashion. Typically, the slider body carries a head and the diamond an opening or socket. Molded integrally with the diamond is an arching locking arm and a pull tab is provided preferably formed of a pair of cords with spaced crosspieces. The tab is provided with an anchoring end adapted to be trapped under inward flanges at the top of the socket opening, one of the crosspieces being disposed under the locking arm to raise the arm during the pulling of the pull tab. The aforementioned anchoring end prevents overtaxing the locking arm, absorbing the pulling force beyond a preset limited amount borne by the arm. |
