Abstract
A slide fastener slider has a reversed bend spring member mounted on the slider body and having a spring tongue bend reaching through a window in a fastening portion thereof which is opened in one side. This increases the resilient force with which the tooth or pawl engages the coupling member and also allows the spring element to be thinner than the earlier system in which a sheet metal spring is used.
