ABSTRACT OF THE DISCLOSURE A slide fastener having at its top end a slider escape mechanism which comprises a cooperative pair of yieldable top stops, and an extra length of fastener elements carried on one of the stringer tapes, such that the slider can be forced past the yieldable top stops to ride onto the extra fastener elements in an emergency and hence to release the other stringer tape. To permit ready withdrawal of the said other stringer tape from the slider, a reinforcing sheet of thermo- plastic material or the like is heat-sealed or otherwise attached to it's upper end portion, from which at least the bead of the tape is removed. The fastener can be forced open from its top end without pulling the slider down along the rows of interlocking fastener elements.
