Abstract
Safety assembly for a separable coupling device, particularly for a motor vehicle steering column having two coaxially arranged shaft sections whose end portions are offset with respect to their common geometric axis and which overlap. Each shaft section carries a plate. Each plate is connected to the other plate by separable link pins. The safety assembly comprises a clip made up of a fork having two faces connected to each other by a web so that each of the two faces bears against one side of a corresponding plate: one of the two faces has a system for attaching one of the ends of one part of the link pins; the other face has a system for clamping one of the ends of the other part of the link pins; one of the two faces is provided with openings intended to receive the corresponding end of the link pins that are not connected to the face, in such a way that the clip blocks the axial separation of the two plates with respect to each other when this separation occurs at a slow speed frontal impact, while at the same time permitting this separation when a frontal impact occurs at high speed.
