An energy absorption device includes a support, a dissipating element mounted around the support and being operable to deform plastically under the effect of a shock, and balls mounted with a given pressure against the dissipating element and intended to deform the dissipating element. The support is provided with grooves, and the balls are mounted opposite the grooves of the support and are operable to deform the dissipating element along the length of the grooves.
