ABSTRACT OF THE DISCLOSURE A slide fastener includes a row of coupling elements secured by sewing stitches to one longitudinal edge of a support tape made of film of plastics material, a non-woven fabric or a thread-free web. The sewing stitches are formed of at least one thread having loops passing through the support tape. The thread is a monofilament. When the fastener of the present invention is subjected to heat-set treatment, the monofilament resists the tendency of multifilamentary threads to flatten out. Consequently, the slide fastener of the present invention provides, after heat-set treatment an improved mechanical strength at the connection between the sewing stitches and the row of coupling elements.
