Abstract: A chain tensioner is provided with a take-up hook (21) connected to the junction area (30) between the shank (3) thereof and double hook end (4) by means of a chain (20). The take-up chain (20) has an end link (23) surrounding the shank material of the tensioner and which is bound by its form between the shank portion (23) on one side and material projections (22) on the flattened end portion (4). The link (23) surrounds the junction area (30) with clearance so that the link (23) can be swung relative to the direction of the shank (3). The link (23) connecting the take-up chain (20) to the tensioner is to advantage made in a C-shape so that the take-up chain (20) with hook (21) can be easily hooked-on to or hooked off the tensioner.

Abstract: A tool for attaching a wire dropper or batten to the wires of a fence line comprises a body having first and second wire engagement devices which are located at substantially right angles to one another. The body includes a lever mounting device which can receive a lever for operating the tool. The tool is used by engaging a fence wire in the first wire engagement device and the wire dropper or batten in the second wire engagement device. The body is then rotated about an axis which is coaxial or parallel with the longitudinal axis of the fence wire so as to wind the wire dropper or batten onto the fence wire.
