The coupling device has a main body to hold a counter part, e.g. a nipple. It also has a control device (9) to alter the medium flow through the passage (15) of the coupling (1), and a shutter (7) with a lock (10) for the counter part. There is at least one control member (18,20) for medium flow variation and for shutter locking. When the shutter is locked, positive flow passage for the medium is continuously adjustable via the control device, and is secured in its setting while the locking is maintained. |
