An upper wing of the slider body has a locking-pawl-insertion hole, a recess forwardly extending from the locking-pawl-insertion hole, a locking-plate-attachment projection disposed at the front side of the recess, and a pair of pull-tab-attachment lugs disposed at opposite sides of the recess. The locking plate having at one end an axle rotatably supported by the locking-plate-attachment projection and at the other end a locking pawl inserted in the locking-pawl-insertion hole. The pull tab has at one end a pintle axle rotatably supported by the pull-tab-attachment lugs and a cam on the pintle for pressing the locking plate in such a manner that the locking pawl can project from the locking-pawl-insertion hole to engage a pair of rows of fastener elements.
