An air brake connection system includes a tractor fitting (18) and a trailer fitting (5). A hose (8) has fittings (21, 11) at its opposite ends that are uncouplably connectable to the tractor fitting (18) and to the trailer fitting (5). Each tractor fitting (18, 19) may incorporate a self-sealing valve. In use, if an air hose fails, it can be simply uncoupled from both tractor and trailer and replaced with a spare hose. |
