<p>A coupling element for a slide fastener comprises a head portion of substantially uniform thickness, and a coupling prosection projecting from one surface of the head portion. pair of tape edge clamping legs extend from the head portion in spaced-apart relation to each other. The legs have inner flat surfaces which face each other and are adapted to grip a tape edge in surrounding relationship therewith, and a pair of outer convex surfaces which face away from each other and with which a slider is slidably engageable when the latter is manipulated to open and close the slide fastener. Each of the legs is transversely tapered from the outer surface toward the inner surface to provide trapezoidal transverse cross-sectional shape thereof. A method of making the coupling element is also provided.</p> |
