  • Reclosable couplings
    Patent number: 4733441
    Abstract: Reclosable couplings are provided wherein a pair of first side portions of a link lap one another when the link is closed by means of a collar. Peripherally, the collar passes around the lapped first side portions and around a continuous second side portion of the link and is between a pair of stops connected with the first side portions of the link. The second side portion of the link is interconnected with the first side portions through a pair of bight portions. Meanwhile, the collar and the stops are relatively movable, for either of the first side portions and the related stop to be selected and deflected toward the second side portion of the link, so that the collar can be moved along the other first side portion of the link until the one of the first side portions and the related stop are outside the opening in the collar, thereby opening the coupling.
