Coupling for fluid-conducting lines

A coupling arrangement for connecting a first and a second thermally insulated, fluid-conducting line comprising:

• a coupling having a first coupling part arranged at the first fluid-conducting line;
• a second coupling part arranged at the second fluid-conducting line;
• and
• connecting means for releasably connecting the two coupling parts, wherein a covering surrounding the coupling parts is provided, wherein a cavity formed by the covering is configured for avoiding the condensation of atmosphere which has penetrated into the cavity, wherein the covering comprises a first and a second hood, a first end of the first hood abutting the thermal insulation of first fluid-conducting line and a first end of the second hood abutting the thermal insulation of second fluid-conducting line, wherein respective second ends of the first and the second hood are releasably and directly connected to each other over the coupling parts, wherein the respective second ends of the first and the second hoods each extend, in an axial direction of the fluid-conducting line, at least up to a separating plane of the coupling, wherein in the separating plane, the first and the second coupling parts are detachable from each other, wherein the covering has an inlet or outlet opening for configuring the cavity to void the condensation of atmosphere which has penetrated into the cavity, wherein, in order to configure the cavity to avoid the condensation of atmosphere which has penetrated into the cavity, media which do not condense at a temperature occurring on a surface in the interior of the covering during operation are introduced into the cavity via the inlet opening, and wherein the covering is composed of an electrically non-conductive material, and is connected to the thermal insulation of the fluid-conducting line via an electrical insulator, and/or an electrical insulator is arranged between the hoods.
