ABSTRACT:
An automatic locking slider for slide fasteners comprises a slider body including a pair of upper and lower wings joined together, the upper wing having a pair of opposed lugs provided protuberantly on its upper surface; a locking member fitted between the lugs and pivotted at its middle to thereto, the locking member having at its lower end a locking prong; a spring member provided on the slider body for normally urging the front end of the locking member upwardly so as to bring the locking prong into locking disposition; and a pull tab for pulling up the rear end of the locking member so as to bring the locking prong out of locking disposition for reciprocation of the slider. The lugs are so bluged roundedly as to have their respective outer sides to extend substantially to and merge into the edge of the front end and as to substantially enclose a front half of the locking member on its opposed sides.
