Disclosed is a damping device to be incorporated into fluid systems, particularly hydraulic systems, said damping device comprising an expansion hose (2). An essentially rigid damper pipe (15) which is oriented counter to the direction of flow is disposed inside the inner space of said expansion hose (2). The damper pipe (15) is provided with a completely closed wall, resulting in a good damping effect. Preferably, the damper pipe (15) is significantly less flexible in the radial direction than the outer expansion pipe, whereby the damping effect is substantially enhanced.
