Beschreibung
Zusammenfassung:	A device for connection of double-wall pipes including an interior connection system connecting the first and second interior pipes and an exterior connection system including a first part that cooperates with an end section of the first exterior pipe and a second part that cooperates with an end section of the second exterior pipe. The exterior connection system is configured so that at a first temperature at least one of the first and second parts exerts a contact force on the end section of the corresponding first or second exterior pipe greater than at a second temperature higher than the first temperature in order to reinforce the seal, especially in the event of a hydrogen leak when hydrogen is present in the first and second interior pipes.
