Abstract

A tensioning device, especially for lashing chains. The device is provided with two link members, movable with respect to each other and having a releasable latch for receiving chain members. At least one link member has a fork-shape, including two legs or arms projecting to extend freely and parallel to each other while being connected by a transverse piece. The link members are held under tension in the closure position, and at least one link member is movable into a releasing position under the force of the connected tension chain. Two spindles are journalled in a double nut, with each having self-binding left and right threads for movement of the link members. A yoke or bracket bridging a suspension opening formed by a hook can be provided, with the hook being pivotable to serve as a link member. The hook is releasably connected with its free end on the yoke or bracket. The hook may be extended beyond the pivot axis thereof.
