ABSTRACT OF THE DISCLOSURE A lockable slider fastener of the type including locking mechanism having a drum rotatable about an axis generally perpendicular to the plane defined by the Y- configuration of the slider channels for passage of fastener elements. One face of the cylindric drum defines a cam surface for actuating one end of a locking lever whose opposite end forms a locking bolt element for engagement with slider elements to lock the fastener, the drum being urged away from the plane of the "Y" by an axial spring. Contrary to prior art slider wherein the drum engages the locking lever only such as to move same out of locked position, while the elements engaging movement is effected by a separate spring, the invention couples the cam drum engaging end of the lever to the axial spring such that the axial spring is utilized both in urging the drum and the lever into its locked position, either directly or with the drum as an intermediate. The invention simplifies the structure and provides for a slimmer, more elegant overall configuration of the slider.
