A device for damping movement of a telescopic guard including a plurality of box-shaped cover elements which slide inside each other in a defined direction. A plurality of leaf springs respectively connect the rear edges of the box-shaped elements to the rear edges of adjacent box-shaped elements. A guide rod is connected to each box-shaped element and is slidably connected to the adjacent box-shaped element. The guide rod slides in a friction element attached to an adjacent box-shaped element. Two circular bellows are fitted around the rod.
