ABSTRACT:
A coupling device has two connectable and disconnectable units. A first unit is provided with a centrally arranged body and an inner casing slidingly arranged between two positions. In a first position, the inner casing cooperates with the central body to keep closed a passage for a fluid medium through the first unit. A second unit has a front section interactable with the inner casing in order to force the casing to a second position against the force of a spring which urges the casing towards the body. In the second position of the casing, the passage for the fluid medium is opened. The second unit also has a valve which closes a passage for the fluid medium when the units are in the disconnected position and opens said passage when the units are in the connected position.
