A composite air and electrical coupling for a vehicle having a plurality of electrical inputs, an air supply and a control air conduit and a trailer having a plurality of electrical outlets, an air reservoir, a control air conduit and air actuated brakes, comprising: a hollow case formed in two laterally telescoping vehicle and trailer sections, means releasably locking the two sections together, said vehicle cupped section having first energizing air passage means adapted to be connected to the air supply on the vehicle and separate first control air passage means adapted to be connected to the vehicle control air conduit, said trailer section having second energizing air passage means adapted to be connected to said air reservoir for providing supply air to actuate said brakes and separate second control air passage means adapted to be connected to an air control valve on the trailer for directing air from the reservoir to the brakes, said first and second energizing passage means and said first and second control air passage means being respectively coaxially aligned whereby the lateral telescopic interconnection of the two sections automatically couples the respective passages in operative communication with each other, each said section having electrical terminals, and electrical interconnection means for electrically interconnecting the terminals when the two sections are telescopically interconnected.
