If he was using a leverage bit, the curb chain is attached to the rings on the purchase side (side that attaches to the headstall). It is meant to go under his chin and as the bit is pulled back, it interacts with his chin to give leverage to the bit. Sometimes there will be a second strap or chain by the reins which is a hobble strap meant to keep the shafts of the bit from separating too much.
A strap on a snaffle is meant to keep the bit from being pulled through a horse's mouth and is usually reserved for horses that are green so that if you need to give more then normal contact to turn him, you can't pull the bit through.
