Abstract: An over-center load binding apparatus for interconnecting two tension members and tightening them towards one another, which includes a yoke, a first tension member pivotally connected to the yoke, an elongated pivot arm having a first end pivotally connected to the yoke, a second tension member connected to a second end of the elongated pivot arm, whereby the elongated pivot arm adapted to be pivotal between an open position and a closed position in which the second end thereof to which the second tension member is connected, will pass arcuately around the first tension member to an over dead-center position, a lever arm connectable to the yoke for forcibly pivoting the yoke to dispose the elongated pivot arm in the closed position, a latch for latching the elongated pivot arm in the closed position, and a key lock mechanism incorporated within the yoke for locking the latch while the latch is latching the elongated pivot arm in the closed position.
