ABSTRACT:
A manually releasable, toggle-type fastener is provided for use, in place of the conventional bolt-and-nut fastener that is normally used to secure together the adjacent, aligned, bolt lugs formed on the ends of curved segments which form a circular pipe coupling. The fastener includes a first pin part fitted into the bolt hole of a first lug, and a second pin part fitted into the bolt hole of the second lug. A lever is pivotally connected to the first pin part for swinging into a locked position adjacent its segment and for swinging into an unlocked position away from its segment. The lever has an end to which a clamp member is releasibly secured. The clamp extends along the lugs and has an end which engages the second lug and which carries the second pin part for securing the lugs together. The fastener may be made in different sizes to fit different size bolt lugs on different size couplings. Particularly, the clamp member may be exchanged for different size clamp members for utilizing the same fastener for fastening different size coupling lugs.
