An impact absorber for a motor vehicle comprises a pair of telescopingly interfitted tubes which receive the impact energy axially and in which either the inner or outer tube is plastically deformed as the tubes are telescopingly contacted by the impact force. The outer tube receives a smaller diameter portion of the inner tube at one end and the outer tube projects at this end to have a large diameter portion whose diameter is greater than the inner diameter of the outer tube and is connected to the small diameter portion by a conical transition region.
