Abstract: The invention relates to a coupling for connecting vacuum-insulated line ends (12, 13) via a coupling socket (11) and a coupling plug (10) which are provided for conveying a cryogenic medium and which have closing elements (28, 29) at the outer line ends that close the line ends. In order to ensure a simple replacement of the gaskets and improved safety during operation and in case of operating errors, the closing elements (28, 29) of both line ends (12, 13) are directly adjacent to the separation plane (27) of the coupling socket (11) and of the coupling plug (10).

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.
