A coupling device for conveying cryogenic fluid which is separable in the event of an emergency and is automatic-closing, the device comprising: two pipes for conveying fluid that extend in a longitudinal direction and each comprise, at a connection end, a valve mechanism that is configured to automatically close the pipe when the connection ends are separated and to allow the pipe to open when the connection ends are coupled; an outer tube that is arranged around each conveying pipe and defines an evacuated space for thermally insulating the conveying pipe; a quick-connection mechanism for quickly connecting the two pipes which comprises cooperating mechanical fastening members that are located at each of the two connecting ends, respectively; an emergency separation system that is configured to allow the two pipes to be separated when the connection ends are coupled via the quick-connection system, wherein the emergency separation system is located at a connection end of a first pipe and comprises a set of connecting parts that are movable between a first configuration, which provides a rigid mechanical connection between the connection end that is equipped with one or more fastening members of the first pipe and the rest of the first pipe, and a second, split configuration in which the connection end of the first pipe that is equipped with one or more mechanical fastening members of the quick-connection mechanism is separated from the rest of the first pipe.
