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).
