Depends on what type of tractor and trailer you had in mind. For a farm tractor pulling a trailer, it's usually a pintle on the tractor which is run through a clevice on the trailer.

In the case of an 18 wheeler, air lines will connect from the tractor to the trailer to operate the trailer's air brake system.
