- wherein a plurality of said catch portion extend in the respective locking hollow portions to engage the respective resilient hook-shape ends in the direction of thickness of said fastener tape.
- 10. A slide fastener according to claim 5, wherein said locking hollow portion has an escape through hole in its wall at a position confronting said resilient hook-shape end.
- 11. A slide fastener comprising:
- (a) a pair of fastener stringers each having a fastener tape and a row of coupling elements mounted on and along an inner edge of said fastener tape for being coupled with the coupling element row of a companion fastener tape;
- (b) a slider removably threaded on said pair of fastener stringers;
- (c) a split arrester composed of male and female members to be interlocked when said slider is removed from said fastener stringers, said male and female members being mounted on the respective inner edges of the opposed fastener tapes at positions contiguous to top ends of said coupling element rows, each of said male and female members being substantially equal in thickness and width to said coupling elements;
- (d) said male member of said split arrester having an attachment base portion attached to one of the opposed fastener tape and a generally T-shape locking tongue portion projecting from said attachment base portion toward said female member, said T-shape locking tongue portion having at its distal end a protuberance bulging in opposite directions longitudinally of said fastener tape to define a neck; and
- (e) said female member of said split arrester having an attachment base portion attached to the other fastener tape with a generally C-shape locking portion formed therein in which said locking tongue portion is received and held at front and rear sides of said neck thereof, with first and second catch projections provided on opposed inside wall surfaces of said locking portion toward each other for engaging said protuberance of said locking tongue portion being provided at an open end of said locking portion, at least one of said first and second catch projections being a separate metallic spring for pressing the front or rear side of the neck resiliently;
- wherein said locking portion has a recess on an inside wall surface thereof for receiving said protuberance of said locking tongue portion.
- 12. A slide fastener comprising:
- (a) a pair of fastener stringers each having a fastener tape and row of coupling elements mounted on and along an inner edge of said fastener tape for being coupled with the coupling element row of a companion fastener tape;
- (b) a slider removably threaded on said pair of fastener stringers;
- (c) a split arrester composed of male and female members to be interlocked when said slider is removed from said fastener stringers, said male and female members being mounted on the respective inner edges of the opposed fastener tapes at positions contiguous to top ends of said coupling element rows, each of said male and female members being substantially equal in thickness and width to said coupling elements;
- (d) said male member of said split arrester having an attachment base portion attached to one of the opposed fastener tapes and a generally T-shape locking tongue portion projecting from said attachment base portion toward said female member, said T-shape locking tongue portion having at its distal end a protuberance bulging in opposite directions longitudinally of said fastener tape to define a neck; and
- (e) said female member of said split arrester having an attachment base portion attached to the other fastener tape with a generally C-shape locking portion formed therein in which said locking tongue portion is received and held at front and rear sides of said neck thereof, with first and second catch projections provided on opposed inside wall surfaces of said locking portion toward each other for engaging said protuberance of said locking tongue portion being provided at an open end of said locking portion, at least one of said first and second catch projections being composed of resilient material for pressing the front or rear side of the neck resiliently;
- wherein said female member is made of synthetic resin material and said locking portion has a vertical through hole at a position toward said second catch projection so that a through hole-side part of said locking portion is resiliently deformable entirely.
- 13. A slide fastener comprising:
- (a) a pair of fastener stringers each having a fastener tape and a row of coupling elements mounted on and along an inner edge of said fastener tape for being coupled with the coupling element row of a companion fastener tape;
- (b) a slider removably threaded on said pair of fastener stringers; and
- (c) a split arrester composed of male and female members to be interlocked when said slider is removed from said fastener stringers, said male and female members being mounted on the respective inner edges of the opposed fastener tapes at positions contiguous to top ends of said coupling element rows, each of said male and female members being substantially equal in thickness and width to said coupling elements;
