ABSTRACT:
Disclosed is a lockable slider for a slide fastener in which but a single spring is provided on the fore thereof that has double functions to urge a cylindrical member upwardly for enabling the rotation thereof by a separate key and to simultaneously bias the fore end of a locking lever pivotally supported at its middle upwardly to pivot it in such a way to intrude a locking pawl formed at the rear end thereof into engagement with fastener elements, thus locking the slider relative thereto. The lockable slider thus permits to be the more compact in its rear, rendered itself the more attractive in appearance compared with the prior art slider equipped with two springs, one on the fore and the other on the rear thereof.
