The invention relates to a kinetic energy absorbing mechanism for a shock absorber or barrier end on the road, by means of the longitudinal propagation of the plastic deformation of at least one deformable longitudinal metallic profiled element, generated by means of a rigid ram that moves along the deformable profiled element, intercepting part of its cross-section, connected to a structural element of the system that receives and transmits the impact of the vehicle by moving along the restraining system. The deformable profiled element is directly or indirectly fixed in the ground, thereby remaining static during the impact.
