An automatic lock slider 1 for a concealed slide fastener comprises a slider body 3 , a locking lever 5 and a knob 11 . The locking lever 5 is pivotally mounted on the slider body 3 . A locking pawl 53 on one end 55 of the locking lever 5 is urged into a fastener element guide channel 39 of the slider body 3 by a spring 7 , to prevent unintentional sliding of the slider 1 along a slide fastener. The knob 11 is attached to a connecting ring 9 through which the locking lever 5 is inserted. When opening or closing the slide fastener, the knob 11 rocks and lifts the locking lever 11 to withdraw the locking pawl 53 from the fastener element guide channel 39 , thereby allowing movement of the slider 1 along the slide fastener.
