The crash box is configured in the form of a hollow body made of two sheet-metal shells which overlap one another in an overlap zone and are interconnected, at least in sections thereof, through material union. The cross member is detachably secured to the crash box by a bolted connection having at least one bolt which extends in upright direction of the motor vehicle and is arranged in the overlap zone of the crash box. Force introduction from the cross member into the crash box is hereby improved.
