I claim the ornamental design for a pull tab for a slide fastener slider, as shown and described herein.
FIG. 1 is a front view illustrating the pull tab of a slide fastener;
FIG. 2 is a bottom view of the pull tab;
FIG. 3 is a top view of the pull tab;
FIG. 4 is a left side view of the pull tab;
FIG. 5 is a right side view of the pull tab;
FIG. 6 is a section view of the pull tab taken along the line 6—6 of FIG. 1; and,
FIG. 7 is a front view, the broken line showing the slider of a slide fastener is for illustrative purposes only and forms no part of the claimed design.
