A coupling element for slide fastener is formed from a monofilamentary material such as polyester, nylon and like thermoplastic resins into a continuous meandering or zig-zag structure having a substantially semi-circular transverse cross-section, the coupling element having a coupling head, an upper leg and a lower leg extending oppositely from said head in parallel spaced apart relation and a heel interconnecting each of the upper and lower legs. The heel is oriented by rotation through 90° or 180° and protrudes at least in part beyond the outer surface of the leg thereby providing increased surface area of the heel for sliding contact with a slider.
