ABSTRACT For a simple operation and high safety in a coupling for fluids under pressure, an arrangement of an inlet valve, a ventilation valve and an outlet valve in the coupling housing is proposed, the inlet valve, and ventilation valve being brought alternately into the open position by an operating device, e.g., an eccentric shaft. Due to this alternate blocking of the valves, at least one valve is always closed even on faulty handling, so that fluid under pressure cannot escape. This coupling is thus suitable especially for high pressure filling at filling stations, since high safety and simple operation are achieved. A simplified coupling is described, which can be operated by hand, enabling fast coupling and disconnection, so that fluid cannot flow out.
