A coupling 10 comprising an elongate arm 14 secured at one end to a coupling panel 16 and pivotably connectable at the other end to a trailer 12. The arm is displaceable between an engaged position (dotted lines) adjacent the trailer for travelling, and a disengaged position (solid lines) with the arm extending away from but not beyond the side of the trailer, for coupling supply lines 28. The panel may include a front 17 with electrical connectors 20a-d and airlines 22a,b, and walls 24, 26 forming an open chamber at the back (figure 5). The arm may be a C-shaped channel for the cables. The pivot may be a pin and clevis (38, 40; fig. 3) at an offset angle (theta, fig. 3) from the trailer. There may be a handle 52, which locks into holes (70, 72; figs 2, 4) via a spring-biased (74, fig.2) rotational lifting mechanism (58, fig. 2), and may also be secured in place (80, 82, fig. 3). There may be a gas strut (84, fig. 4) to assist in arm movement, and an alarm 86 connected to a proximity sensor (88, fig. 3). Also claimed are methods of coupling and uncoupling the lines.
