A slide fastener slider whose flanged top and bottom plates are fixedly connected by a wedge or neck to define a branched passage for a slide fastener chain through the slider. A latch is secured to the top plate outside the passage for angular movement about an axis transverse to the normal direction of slider movement. The latch includes a detent passing through an aperture in the top plate and having first and second opposite faces transverse to the direction of slider movement which converge inward of the passage toward a free end of the detent, the first detent face being directed away from the neck. Abutments on the top plate and the latch limit the angular movement of the latter. In one terminal latch position, the first detent face is approximately perpendicular to the direction of chain movement in the passage, and the free end of the detent projects into the slider passage and toward the bottom plate. In the other terminal position, the end of the detent projects farther into the passage and is nearer the bottom plate then in the one position. A pull is secured to the latch. |
