A tow bar particularly adapted for use with tailwheel aircraft which includes an elongated rod, a handle at one end, a pair of clamping members pivotally connected at an opposite end, the clamping members each being of a generally u-shaped configuration defined by a pair of spaced arms, a bight therebetween, and a tail, a pivot pin connecting the clamping members to the rod, first and second arms of each clamping member having respective first and second noses, the first noses being overlapped in a closed position of the clamping members to embrace a tailwheel aircraft tailspring therebetween, the second noses of each clamping member being effective to contact the aircraft tailwheel tailspring to move the clamping members from an open to the closed position thereof, and an over-the-center spring for holding the clamping members in the open position and biasing the clamping members to the second position after passing an over-the-center plane through the pivot.
