A needle locking structure of a zipper slide for engaging or disengaging two lengths of teeth on two opposite teeth tapes is provided. A monolithic main body has two joint portions formed thereon. An engagement part is formed on each side of the main body. A spring piece is fixed by the joint portions of the main body. A pull tab unit is fixed by the joint portions of the main body for facilitating the manipulation of pulling the zipper slide. A laterally shifted extending portion is provided at one end of the spring piece. Since the extension portion jabs the top of an engagement line of one of the teeth tapes, the friction force is increased whereby improving the positioning of the main body and preventing unwarily sliding of the zipper slide.
