Abstract
A coupling device has two connectable and disconnectable coupling parts. A first of said coupling parts is provided with a centrally arranged body and an inner casing slidingly arranged between two positions relative to the central body. In a first or disconnected position, the inner casing cooperates with the central body to keep closed a passage for a fluid medium through the first coupling part. A second of said coupling parts has a front section interactable with the inner casing in order to force the inner casing to a second position against the force of a spring which urges the casing towards the body. In the second or connected position of the inner casing, the passage for the fluid medium is opened.
