ABSTRACT:
The invention relates to An anchoring device that is intended for, for example, the roof of a building. The inventive device comprises: a base which is used to fix to roofing; a hook element which is mounted to the base at one end thereof and which comprises a hook ring at the other end; a tilting mechanism which, in the event of an impact, enables the hook element to tilt in a normal plane in relation to the plane of extension of the base; a damping mechanism which is used to absorb energy during the tilting of the hook element. The damping mechanism comprises a trigger mechanism that can be used to prevent the hook element from tilting when the element is subjected to a force having an intensity that is lower than a pre-determined threshold. The aforementioned trigger mechanism comprises a removable part which is different from the other elements making up the damping mechanism.
