The invention relates to an expansion joint () for joining two adjacent parts of a pipe. The expansion joint () comprises an expansion bellows (), an expanded wall () and an inner sleeve assembly (). The expanded wall () comprises a first wall part () and a second wall part (), wherein the first wall part () and the second wall part () are spaced apart from each other axially by an axial gap. The expansion bellows () is connected to the first wall part () and to the second wall part () such that the axial gap between the first wall part () and the second wall part () is closed and such that the first wall part () and the second wall part () are connected flexibly. The expanded wall () and the inner sleeve assembly () limit at least one sealed chamber () between each other, and the at least one sealed chamber () is filled by a first gas.

Expansion joint

Proposed is a line assembly (), including: a metal hose () that is corrugated at least in some segments; and an inner component (), which is arranged radially inside the metal hose at least over a partial length of the metal hose; the line assembly being distinguished by at least one coupling element ('), which coupling element is arranged between an outer border () of the metal hose () and an outside surface () of the inner component () and which coupling element is designed to damp the metal hose () by means of mechanical coupling to the inner component ().
