ABSTRACT OF THE DISCLOSURE There is provided a molded coupling element for a slide fastener, comprising a body portion for being secured to an edge portion of one carrier tape of a slide fastener, and a locking portion including a head portion and a neck portion extending from the body portion for interlocking with locking portions of mating coupling elements on an opposite carrier tape of a slide fastener. In order to increase the head bearing area without decreasing flexibility the head portion includes locking protrusions having distal edges extending perpendicular to the one carrier tape for providing increased bearing area with mating locking protrusions of mating coupling elements, and the neck portion of the locking portion has recesses for receiving the locking protrusions of mating coupling elements and has inner surfaces defining inner boundaries of the recesses formed with a taper relative to a perpendicular to the one carrier tape to provide for working clearance and flexibility of the coupling element in a slide fastener.
