A martingale.
A breast collar is used for the sole purpose of helping to keep the saddle from twisting around on a horses back. It helps with horses that don't have very prominent whithers, and barrel racers and other such sports use them because they turn at fast speeds. The breast collar helps prevents the saddle from slipping to the side. A martingale is used when a horse constantly throws his head up, and the rider can't keep a horse's head down, so they use the tool instead of actually training the horse to not throw it's head up.
The strap that goes over a horses chest :L It's called a breast plate
Horses cannot throw up& they have no collar bone.

Breast collars for horses are usually made from leather with elastic inserts. For longer distance/endurance riding, breast collars can be made from synthetic fibers.
A simple answer is the harness and traces. A harness is placed on both horses. The horse (or horses) is attached to the vehicle by the traces. The traces come from the collar or breast collar, along the side of the horse and they attach to the vehicle by the heel chains, a short length of chain at the end of each trace. The traces is attached by the heel chains to the singletree on the vehicle.
