Abstract: A slide fastener has a pair of stringer tapes and coupling members each fastened to the stringer tapes in a row. The rows of coupling members lie opposite one another and connect the two stringer tapes to one another in an interlocking manner. Each stringer tape is formed from two stringer tape portions, the coupling members each rest against a first stringer tape portion, and a second stringer tape portion is arranged on the side of the first stringer tape portion facing away from the coupling members. The first stringer tape portion and second stringer tape portion of stringer tapes are bent and connected to each other at a stringer tape region. A slider is designed such that a movement of the slider in a first direction connects the coupling members of the stringer tapes in an interlocking manner and releases them in an opposite direction.
