Abstract
This reinforcement has at least one elongated slit 12 formed in the wall of the tube 1 located inside the reinforcement and therefore little exposed to impacts. The slit 12 is formed by a punching operation by urging back the material toward the interior of the tube and rolling it in the form of two curls in opposite directions. Upon impact, the reinforcement is progressively deformed in the region of the slit and thus absorbs the energy of the impact.
