Abstract

A plug-in coupling for cryogenic lines is described, having at least two pipes (3, 4, 9, 10) fitted one inside the other like a male/female connection while forming an annular gap (16), in which plug-in coupling the pipes (3, 4, 9, 10) are releasably connected to one another by a flange connection (5, 11) located at their “warm” end, the annular gap (16) between the two pipes (4, 9) is sealed at the “cold” end by an annular seal (7) and at the “warm” end by an annular seal (5d) located in the region of the flange connection (5, 11), and the annular gap (16) is connected to a safety valve (13) in the region of the flange connection (5, 11).
