ABSTRACT OF THE DISCLOSURE There is disclosed a stringer for a slide fastener and a method of forming such a stringer, the stringer comprising a tape, and a train of molded and folded synthetic polymer coupling elements disposed along one longitudinal edge of the tape. Each of said coupling elements has a head portion and a pair of leg portions which extend in the same direction from opposite sides of the head portion, said leg portions terminating in heels thereof opposite to the head portions. First and second pairs of connecting threads have segments embedded in the respective leg portions and connect the coupling elements in the train, said leg portions being bonded together adjacent their heels. A securing thread extends around the pairs of connecting threads between the coupling elements and secures the train of coupling elements to the one edge of the tape. The coupling elements each include a half-groove formed in each of the heels of the leg portions forming a full groove in the joined heels of the leg portions, said groove extending longitudinal to the tape, and a support cord in the one edge of the tape lying in the grooves of the coupling elements.
