Abstract:
A line element for an exhaust pipe includes an inner hose, and an outer hose which is disposed in surrounding relation to the inner hose such as to form an intermediate space. At least one of the inner and outer hoses is formed from a wound profiled band. The band includes a radial projection which projects into the intermediate space and forms a spacer between the inner hose and the outer hose.
