The invention relates to an energy dissipator (1) comprising at least one generally loop-shaped tubular element (2) having first and second ends (3, 4) connected to each other by the intermediate of a connecting element (5), the tubular element (2) being intended for the passage of a cable (10) and being arranged such that part of the traction energy of the cable is dissipated by deformation of the tubular element (2) during the pulling of the cable. The first and second ends (3, 4) are fixed to the connecting element (5), so that the tubular element deforms in accordion by buckling during the pulling of the cable.
