In an automatic lock slider for a slide fastener, a yoke accommodating a locking pawl and a leaf spring has a pair of inwardly directed projections, and a generally C-shaped, narrow rigid strip has on its upper edges a pair of taper surfaces corresponding to the respective projec- tions. As the taper surfaces are guided by the projections, the pawl keeps its suitable posture during the assembling of the slider, and the pawl acts reliably while the automatic locking mechanism is either operative or inoperative. The locking pawl is small in width and has one leg portion to be inserted in a groove of the outer surface of a connector of a slider body. The result is that the number of pressing steps is reduced to minimize press traces on the surface of an upper wing of the slider body so that press traces are prevented from coming out on the slider surface though the yoke is smaller in width compared to the conventional one.

Dans un curseur bloqueur automatique pour une fermeture à glissière, une chape accommodant un cliquet de verrouillage et une lame ressort comporte deux saillies intérieures, et une bande rigide étroite en C comprend sur ses bords supérieurs deux encoches correspondant aux saillies. Puisque les encoches sont guidées par les saillies, le cliquet maintient sa position durant l'assemblage du curseur, et il agit de manière fiable pendant que le mécanisme à blocage automatique est en état de fonctionnement ou hors service. Le cliquet de verrouillage est étroit et comprend une patte à insérer dans une rainure sur la surface extérieure d'un connecteur du corps du curseur. Le résultat est que le nombre d'étapes de pressage est réduit pour minimiser les empreintes laissées par la presse sur la surface de l'ailette supérieure du corps du curseur de façon que ces empreintes n'apparaissent pas sur la surface du curseur même si la chape est plus étroite que la chape standard.
