<p>A bridge top stop for slide fasteners comprising: a body including a sidewall inwardly curved to define a substantially inverted U-shaped opening and a pair of plates connected at one edge by the sidewall, each of the plates including a pair of laterally spaced first and second wing portions extending away from said opening and forming in confronting pair together with the sidewall a pair of grooves for receiving therein the reinforced edges, respectively; a bulged rib projecting from the sidewall into the opening and extending longitudinally along the sidewall; and ridges disposed on the respective free ends of the wing portions and extending longitudinally along the grooves respectively for clamping engagement with the stringer tapes. The bridge presents an improvement over prior art in that it is capable of maintaining a pair of stringer tapes in a predetermined relation even when the stringer tapes are subjected to a relatively severe lateral pull.</p> |
