ABSTRACT:
A slider for use with a ladder-type slide fastener is disclosed which comprises a pair of opposed flanges and means of locking the slider in place against unintentional movement under the influence of a force tending to spread open the fastener. The locking means comprises a locking lug extending from either one of the flanges and adjacent first and second locking projections extending from either one of the flanges opposite to the locking lug, the first and second locking projections being spaced one element pitch apart such that the locking action is effected at either of the two projections in the event that the fastener coupling elements in one row are shifted out of the normal pitch relation to those in the other row.
