ABSTRACT OF THE DISCLOSURE A separable slide fastener comprises a pair of oppositely disposed stringers each having a support tape and a fastener element formed from a plastic monofilament into a continuous Image structure having coupl- ing head portions, upper legs, lower legs and connecting heel portions and secured by sewn seams to a longitudinal inner edge of the respective tape, a reinforcing core extend- ing through the coiled fastener element and a slider haying a pair of branched guide channels defined between its flanges and diamond. A group of successive loops of the fas- tener element are fused together over a predetermined length at one end of the fastener and cut closely along the sewn seams to provide a pair of integrated pin members on the respective stringers. The group of fused loops on one stringer has a plurality of coupling head portions trans- ferred from the other stringer. One of the pin members includes a locking lug having a transverse length substantial- ly equal to or slightly greater than the width of one of the branched guide channels of the slider.
