A fastener element for a concealed type slide fastener having a substantially U shaped section including a side edge portion mounting groove for a fastener tape, comprising: a C shaped base portion; flat first and second tape nipping portions extended substantially in parallel from respective front ends of the C shaped base portion; and a coupling portion integrated with an engaging face side on the opposite side to a tape nipping face of the second tape nipping portion, wherein the first tape nipping portion has expanded portions expanded back and forth in a coupling direction, and a front end face of the first tape nipping portion is formed wider than a front end face of the second tape nipping portion, thereby having excellent concealed property and coupling strength and capable of preventing generation of a gap between right and left fastener tapes even if pulling stress is applied.

In a Y bar for forming coupling elements, an opening angle of a pair of right and left leg parts is narrower than that of the ordinary ones. Plural bent portions, which are bent inward, are formed successively in an extending direction of the leg parts in a range from a crotch part toward pawl parts at front ends of the leg parts. The gap between the pawl parts are narrowed gradually from proximal ends to front ends thereof. Bulging portions are provided on outer side surfaces of the crotch part. Thus, the stabilization of the posture of a metallic coupling element, which is obtained by cutting the Y bar, at the time of mounting, strength of the coupling element and stabilization of the mounting posture of the coupling element to the fastener tape can be improved.

A slide fastener stringer includes a stringer tape of a warp-knit structure and a series of discrete or separate fastener elements mounted on and along one longitudinal edge of the stringer tape. The stringer tape has a reinforcing cord laid therein or inserted in an outermost groove between adjacent two wales of the tape, the cord extending warpwise and being thicker than the threads forming the tape fabric. The reinforcing cord is stitched with lock or double locked stitches at intervals spaced along the tape, thereby providing an element-anchoring bead on the tape. A pair of additional threads are preferably interlaced with the stitches and are disposed on the flat surface of the tape.

There is provided a slide fastener having a pair of oppositely disposed carrier tapes each carrying on and along one longitudinal beaded edge a series of discrete fastener elements. The fastener elements are each provided with a coupling head and a pair of legs extending from the coupling head and having oppositely disposed inner wall portions. There are formed a plurality of ledges integral with the element legs and projecting from the oppositely disposed inner wall portions. The ledges are smaller in thickness than the element legs.

A link for a slide fastener, the links of which are secured to two binding strips by locking beads along the strip edges in grooves of the links. These grooves are formed on two opposite sides of each link and the two branches defined by each of the grooves are lengthwise slotted parallel to the grooves thereby forming two inner tabs and two outer tabs on each of said sides. The inner tabs are clamped against the beaded strip portion inserted into the grooves thereby locking the links to the respective strip. The outer tabs which are left unchanged conceal the deformation of the inner tabs so that the links present a smooth and ornamental appearance on the outside of the fastener.
