Abstract: A protection device (5a) for motorcyclists, adapted to be secured to a road safety barrier (1) with a plurality of poles (3) regularly spaced out, the protection device (5a) including a longitudinal beam (6a) and a spacer (7a) extending longitudinally alongside the rear side of at least one part of the beam (6a) and adapted to be secured to the poles, wherein the beam (6a) and the spacer (7a) are assembled together so as to define, in the part of the beam, a longitudinal damping volume (V) with a closed cross-section.
