An energy-absorbing device, in particular for a rail-car, extends along an axis and has an attachment member, which can be connected to a fixed structure, an impact member, designed to withstand an impact, and an energy-absorbing member, constituted by a first tube and a second tube, which are coaxial and are made of composite material in order to collapse and hence absorb energy in the event of impact; the first tube is fixed to the attachment member, whereas the second tube is fixed to the impact member and is axially slidable, during impact, guided by the first tube; the radial thickness of the two tubes decreases along the axis, towards their free ends; in a non-collapsed resting condition, the axial gaps present between the two free ends and the attachment and impact members are substantially the same so that the two tubes start to collapse simultaneously in the event of impact.
