The present invention relates to an energy-absorbing device (1) for the bumper beam of a motor vehicle, the energy absorbing device (1) being designed to make the connection between a bumper beam (2) and the end of a vehicle side member (3) facing the bumper beam (2), the energy-absorbing device (1) comprising at least one first zone (4) made of a non-reinforced polymer material and at least one second zone (6) comprising a first nominal layer (16) made of a fibre-reinforced polymer material. According to the invention, the second zone (6) has at least one additional layer (14) which is superposed at least partially on the first nominal layer (16) so as to vary the thickness (ef) of the second zone (6).
