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 (
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).

1. A plug-in coupling for cryogenic lines comprising: at least two parts, a first male part and a second female part fitted one inside the other like a male/female connection while forming an annular gap, wherein within said plug-in coupling, the parts are releasably connected to one another by a fl
1. A plug-in coupling for cryogenic lines comprising: at least two parts, a first male part and a second female part fitted one inside the other like a male/female connection while forming an annular gap, wherein within said plug-in coupling, the parts are releasably connected to one another by a flange connection located at their warm end, the annular gap between an outer pipe of said male part and an inner pipe of said female part is sealed at the cold end by an annular seal and at the warm end by an annular seal located in the region of the flange connection, and the annular gap is connected to a safety valve in the region of the flange connection, said safety valve configured to release excess pressure from air and cryogenic medium trapped in said annular gap proximate said flange connection at said warm end of said first and second parts. 2. The plug-in coupling as claimed in claim 1, wherein the end of the female pipe is widened in its inside diameter, in that the male pipe penetrates into this widened region, and in that the seal provided at the cold end is clamped in place between a transition region from the smaller to the larger inside diameter and the end of the male pipe by a force acting in the longitudinal axial direction. 3. The plug-in coupling as claimed in claim 1, wherein the safety valve is connected to the annular gap via a pipe length let into the flange of the female pipe in a gastight manner. 4. The plug-in coupling as claimed in claim 1, wherein the two flanges of the flange connections are elastically prestressed.
