Stop member for slide fastener includes: a main body having first and second surfaces; a first superficial region formed at a side of the first surface of the main body; and a slit or interface interposed between the first and second surfaces of the main body. The first superficial region extends over and covers the slit or interface, and has a thickness defined between the first surface and an end of the slit or interface at the side of the first surface.

A slide fastener chain includes a first tape and a second tape. A row of coupling elements is fixed along an inner edge of the first tape. A row of coupling elements is fixed along an inner edge of the second tape. The coupling elements of the first and second tapes being arranged such that the coupling elements of the first tape interdigitate with coupling elements of the second tape so as to secure the first and second tapes together. The chain includes a bottom stop. At least one of the tapes is provided with an extension portion which extends beyond a bottom stop portion of the tape. A width of the extension portion is less than a width of a portion of the tape which does not form part of the extension portion.

A slide fastener reinforcing strap for securing across an opening formed between first and second tapes of a slide fastener is provided. The slide fastener reinforcing strap extends from a first end to a second end along a centerline. The slide fastener reinforcing strap includes a first protrusion between the first and second ends. The first protrusion extends in a first direction which is perpendicular to the centreline.

There is provided an end stop. A male member and a female member are configured to sandwich opposing side edge portions of a pair of fastener tapes from both sides thereof in an upward and downward direction. The male member includes a circular disk-shaped male base member and an inserting male portion. The female member includes a circular disk-shaped female base member and a receiving female portion. A facing surface of at least one of the male base portion and the female base portion is provided with a protrusion group. The protrusion group is configured so that a plurality of protrusions protruding to come at least in contact with each fastener tape are arranged to be spaced from each other at predetermined angles over the entire circumference of the facing surface along a circumferential direction thereof.
