A separable end stop for concealed slide fasteners includes a box which has a guide slot extending in a front wall of the box for receiving and guiding folded portions of two stringers, and a retaining recess formed at an upper open end of the box for receiving therein the whole of a lower end portion of a slider body in such a manner that right and left front wall portions extending on opposite sides of the front wall overlap the corresponding wings of the slider body. Each of the front wall portions has an upper end extension projecting from the open upper end the box to ensure that the wings of the slider body are overlapped with the front wall portions of the box. The box further includes a locking portion formed on an interior surface facing a box-pin insertion hole, and a box pin has first and second locking portions on opposite sidewalls thereof, interlockingly engageable with the locking portion and a partition wall, respectively, to assemble the box and the box pin. The separable end stop thus constructed is able to engage engage and disengage two stringers smoothly and reliably and facilitates the sewing attachment between the stringers to an article.

A buckle comprises a plug member and a socket member relasably engageable therewith, the plug member including a retainer means in the form of a disc-like collet and a stopper means adapted to hold the retainer means stationery after the latter is rotated into position in the body of the plug member. The retainer means is normally urged upwardly by a coil spring and serves as a fulcrum about which the plug member and the socket member can be moved rotatably relative to each other.

A strap fastener for releasably connecting a strap, cord or belt on a garment article is disclosed, the fastener comprising a base member, a strap retainer member and a slider. The base member has an upper plate and a lower plate defining therebetween a guide channel through which the slider is movable. The slider has a guide rail at such a lower edge of a side flange which lies above the lower surface of the base member. A hook is formed, extending integrally from the lower plate of the base and releasably engageable with the slider through a ridge-and-groove formation alternately provided on the hook and the slider.

Slide fastener elements made of a helically wound synthetic resin monofilament and the method of forming the same. According to a preferred embodiment, each fastener element comprises an interengaging head arranged on one-line in the longitudinal direction of the slide fastener elements, a pair of interengaging head-side widened portions formed at the both sides of the interengaging head, upper and lower legs extending from the both ends of the interengaging head through the pair of interengaging head-side widened portions respectively so as to transverse the longitudinal direction of the slide fastener elements and a turn extending between an upper leg of one slide fastener element and a lower leg of an adjacent slide fastener element through a pair of connecting portions formed at the both sides of the turn. The interengaging head is formed by pressing the monofilament to be sidened at its portion corresponding to the interengaging head. The interengaging head-side widened portions and the connecting portions are formed by pressing the monofilament to be widened adjacent to the head and the turn respectively and used as the bending portions of the monofilament into the slide fastener elements made of the helically wound monofilament.
