The device (4) has a coupling sleeve (7) for receiving a pair of coupling bodies along a pair of longitudinal axes (LA) of the coupling sleeve. The coupling bodies have a set of fluid ducts extended along a pair of longitudinal axes of the coupling bodies and a set of electrical plug connections. One of the coupling bodies has a valve piston body guided in the coupling sleeve, where the valve piston body is axially displaced when compressed air acts upon the valve piston body. The other coupling body is fixedly received in the coupling sleeve.
