A towing coupler for truck or other vehicle includes a body and a hook. A first latch is coupled to the body for pivoting about a first pivot axis between an open and closed position. In the open position, a draw bar or other towing element of a towed vehicle can be placed on or removed from the hook while in the closed position the first latch retains the draw bar on the hook. A second latch is coupled to the body for pivoting about a second pivot axis between first and second positions. The first latch is biased to pivot toward the open position and the second latch is biased to pivot in the opposite direction from the first latch. The first and second latches have surfaces configured for coupling together to retain the first latch in the position to which it is moved.
