The invention relates to a docking buffer for attaching to ramps, comprising an elastic damping element (3) that is situated between two U-shaped sections (1; 2) consisting of a hard, shock-proof material. The limbs (4; 5) and (6; 7) of said sections are adjacent to one another and can be displaced in relation to one another, the limbs (4; 5) of one U-shaped section (2) converging at an angle .alpha. that deviates from 90.degree. in relation to a base surface (9) and the limbs (6; 7) of the other U-shaped section (1) diverging at an angle .beta. that deviates from 90.degree. in relation to a base plate (8). The opening widths between the ends of the limbs (4; 5) and (6; 7) and the sizes of the angles .alpha.; .beta. are selected in such a way that the limbs (4; 5) embrace the limbs (6; 7). The advantage of the invention is that it provides a docking buffer with a simple construction that is thus cost-effective to produce, said buffer affording reliable protection even during an off-center collision. The greater width of the mobile section in relation to the fixed section creates a larger impact surface for the docking vehicle.
