The hydraulic coupling has a coupler housing and a coupler cartridge displaceably mounted therein such that when the hydraulic plug is pushed in, the coupler cartridge adopts an operating position locking the hydraulic coupling. The arrangement also includes an actuating arrangement. The coupler cartridge is movable via the actuating arrangement from the operating position to an ejection position for releasing the hydraulic plug. The coupler cartridge is actuated by an external force operably controlled by a control arrangement.
