A slider of zipper contains upper and lower covers connected by a crossbar which have boards. The crossbar and boards of both covers form Y-like hollow for displacement of the zipper connection elements. In the upper cover an intermediate is installed which is kinematically connected to a cleat, and a fixer of the slider. The upper cover contains a slot, a cam and a guiding slot. The fixer contains two diametrically opposed stops and a tooth installed in the guiding slot and kinematically connected to the cam. The intermediate has an inner slotand a pusher and is installed in the slot in such a manner that the upper cover contour overlaps the intermediate contour. The stops are kinematicallyconnected to the pusher.
