Abstract
The invention relates to a coupling for connecting vacuum-insulated line ends via a coupling socket and a coupling plug which are provided for conveying a cryogenic medium and which have closing elements at the outer line ends that close the line ends. So that the valve-like means can be opened or closed by remote control in a defined manner, the coupling plug (10) has a control unit (43) that is connected to the closing element (29) and that opens at least the closing element (29) when exposed to control pressure.
