ABSTRACT:
A hitch locking mechanism enables secure retention of a towing vehicle to a towed vehicle. The hitch locking member comprises a shank and a clamp member. The clamp member includes a base, an arm, and a jaw. The jaw is pivotally attached to the base member, and moves relative to the arm between an upright position and an extended position. The shank is securely affixed to the clamp member at multiple points for secure retention of the towing vehicle to the towed vehicle. A first sleeve is positioned about the shank when the shank is retained to the clamp member. The first sleeve enables rotation of the shank relative to the clamp member when the shank is secured within the clamp member.
