A wire clamp device affixed to an outer end of a bar in a wire tightener of the type having a stationary wire holding clamp at an opposite end of the bar. A carrier is mounted on the bar and is also provided with a wire holding clamp. The bar is provided with a jack rack and the carrier has a jack mechanism for forcibly driving the carrier toward the first wire holding clamp so as to pull end portions of two strands of wire held by the two wire holding clamps toward each other. The wire clamp device which also has a wire holding clamp is positioned to hold the strand held by the wire holding clamp of the carrier after it has been drawn towards the first wire holding clamp so that the wire holding clamp on the carrier may be released to allow the carrier to be reset to a position near the wire clamp device, after which the wire holding clamp on the carrier is again activated to grasp again the tightened strand which it had previously held. The carrier can again be driven toward the stationary wire holding clamp at the opposite end after release of the strand from the wire clamp device. The presence of the wire clamp device makes it unnecessary to temporarily fasten the strand being tightened by movement of the carrier in order to allow the carrier to be reset to a position for further tightening of the strand.
