ABSTRACT OF THE DISCLOSURE A slide fastener stringer includes a stringer tape and a series of fastener elements sewn to the tape by means of stitches with upper and lower legs of the elements lying one on each side of the tape. The sewing stitches include a needle thread extending across and over the lower element legs and a looper thread having loops extending through the tape and between every adjacent elements, and interlooped with the needle thread at the side of the tape on which the lower element legs are disposed. The looper thread further includes loops extending over the upper element legs and interlaced with the first-named-loops of the looper thread at the other side of the tape. The advance in the art is in an improved stability and strength of the securement of the elements on the tape. By the same token, the splitting open of a fastener is prevented when any of the stringers is simultaneously bent and subjected to a lateral pull.
