In a slider having a body with an island or separator formed centrally at its flared front end, a locking pawl is arranged between a pair of ears projecting upwardly from the separator in spaced parallelism. A retainer pin extends between the separator ears over the locking pawl in registered relationship to an upwardly opening recess formed adjacent the front end of the latter. Normally, the locking pawl is yieldably urged, as by a leaf spring mounted thereunder to releasably engage the retainer pin in its recess and to have its tapered or pointed rear end held in interference contact with the rows of interfitting fastener elements passing through the slider body. Upon exertion of a pull on a pull tab connected to the locking pawl, the latter will pivot about the retainer pin to permit the free movement of the slider along the fastener elements. |
