ABSTRACT OF THE DISCLOSURE A separable slide fastener comprises A pair of stringer tapes each carrying on its inner longitudinal margins a row of coiled filamentary coupling elements sewn to the respective inner tape margin with a core thread extending through; each of the coiled coupling element rows, and a separable bottom-end-stop assembly mounted adjacent bottom ends of the opposed tapes. The bottom-end-stop assembly includes a pair of separate pin members attached by clinching to the respective inner tape margins at bottom end portions thereof, which portions are devoid of coupling elements and a socket member secured to one of the pin members and having a bore for receiving a portion of the other pin member. Each of the other pin member has a longitudinal channel receiving the element-free bottom end portion of the respective inner tape margin. Before attachment of the pin members, the bottom end portion of each inner tape margin is trimmed along its inner edge that projects inwardly from the core thread. Thus the inner tape margins bottom end portion has a width equal to the width of the channel of the respective pin member and small than the width of the remaining portion of the inner tape margin.
