ABSTRACT OF THE DISCLOSURE There is provided a slide fastener having a pair of oppositely disposed carrier tapes each carrying on and along one longitudinal beaded edge a series of discrete fastener elements made of metal. The fastener elements are each provided with a coupling head and a pair of legs extending from the coupling head and having oppositely disposed inner wall portions. here are formed a plurality of teeth integral with the element legs and projecting from the oppositely disposed inner wall portions such that a first one of said legs comprises two of said teeth, the second one of said legs comprising one of said teeth. The teeth are smaller in thickness than the element legs as measured along the longitudinal direction of the beaded edge. Each of the teeth on one leg is staggered relative to a corresponding tooth on the other leg as measured along the longitudinal direction. The teeth are disposed in gripping engagement with the beaded edge to secure the elements to same. The advance in the art is in an improved stability of the discrete fastener elements on and around the longitudinal beaded edge of a carrier tape. The invention thus provides an improved slide fastener wherein discreet fastener elements are more firmly mounted in position on and around the longitudinal beaded edge of a carrier tape.
