ABSTRACT:
A slide fastener slider includes an arch-shaped lug having a rear free end spaced from the top surface of an upper wing by a first gap larger than the diameter of the spindle of a pull tab, and a closure member slidably mounted in the upper wing and having a first closure projection normally disposed adjacent to the rear free end of the lug to substantially close the first gap. In order to prevent objectionable lateral oscillation of the pull tab relative to the lug without increasing the stroke of the closure member, the lug has on its underside an intermediate partition wall spaced from the top surface of the upper wall by a second gap at least equal to the first gap, and the closure member has a second closure projection normally disposed adjacent to the partition wall to substantially close the second gap. When the closure member is moved forwardly to displace the first and second closure projections, respectively, from the rear free end and the partition wall, the pull tab spindle can pass through the first and second gaps.
