Abstract
In an automatic lock slider for a concealed slide fastener, a fastener-element guide post of a slider body has an upper groove receiving a locking lever and a lower groove slidably receiving a sliding end of a pivoting release member. A spring mounted in the guide post acts on an actuating arm of the locking lever to urge a locking pawl of the locking lever to normally project into a fastener-element guide channel of the slider body. An ornamental knob attached to the pivoting release member covers exposed part of the slider body. As the knob is pulled to pivotally move the release member, the locking pawl is retracted from the guide channel.
