ABSTRACT:
A manually releasable, toggle-type fastener is provided for use, in place of the conventional bolt and nut fastener, used to secure together the adjacent bolt lugs formed on the ends of curved segments which form a circular pipe coupling. The fastener includes a pin of a shape and size to fit into the aligned bolt holes of the lugs, in place of a conventional bolt, and a lever pivotally connected to one end of the pin for swinging into a locked position adjacent its segment and into an unlocked position away from its segment. The lever has a hook-like formation on its end to which a wire-like loop is secured. The loop extends around the sides of the pin and the sides of the bolt lugs to be fastened together and has an opposite end engaging both the pin and the adjacent surface of the segment for securing the lugs together and for being restrained from release by the pin itself. The fastener may be made in different sizes to fit different size bolt lugs on different size couplings and the loop may be exchanged with different size loops for utilizing the same fastener, but with different size loops for different size coupling lugs.
