Abstract
A coupling for connecting a first and a second multi-walled line () having at least two concentric pipes () has a female coupling part () with at least two concentric tubes including an inner and an outer tube () each connected at one end with one of the concentric pipes () of the first multi-walled line (), respectively. The coupling further has a male coupling () part having at least two concentric tubes including an inner and an outer tube () each connected at one end with one of the concentric pipes () of the second multi-walled line (). The at least two concentric tubes of the female and/or male coupling parts are compressible and/or expandable in an axial direction to ensure a fluid tight connection between the male and female coupling part is already achieved when the coupling has not yet reached its operation temperature.
