Abstract
Traction-enhancing tire chains with a lateral cable having a tension-applying connector for interconnecting the opposite ends of the lateral cable for attaching the tire chains to a tire. A clasp is attached to a pin slidably disposed in a cam slot defined in a tensioning lever attached to one end of the lateral cable. The clasp hooks about a selected anchor on the opposite end portion of the lateral cable and applies tension to the lateral cable as the lever is rotated to a tensioning position. The clasp slides along the cam slot and is pivotable with respect to the lever. A hook on the movable end of the lever extends over the lateral cable to hold the lever in the tensioning position. The lever and a hook which is also slidably disposed in the cam slot cooperatively hold excess cable against the side wall of the tire to keep it from flapping about during use of chains incorporating the fastener.
