A tow bar assembly used to tow cars located on uneven terrain. The assembly uses two tow bars. One end of each tow bar is attached to a bumper housing. Each bumper housing is removably clamped to the bumper of a disabled vehicle by a chain which has one end secured to the undercarriage of the vehicle and the other end engaged to a chain hook member. The chain is pulled tight by tightening wing nuts threaded onto the upper end of a bolt which causes a spring located between the wing nuts and the top of the bumper housing to pull the chain tight. A socket member located where the other ends of the tow bars join together engages a ball member mounted on a supporting structure of a tow vehicle providing a universal-type joint. The socket member is secured to the ball member by a rotating latch member which uses a pin to prevent the latch member from rotating relative to the socket member, effectively locking the socket member to the ball member.
