Attachment device to an anchor point and method for using the attachment device

Attachment device to an anchor point comprising:

• a wire-like element comprising a first wire-like element end and an opposite second wire-like element end, the first wire-like element end having a first ring with a first pass-through cross-section;
• a clamp having a first clamp end and a second clamp end opposite the first clamp end, the first clamp end having a smaller first cross-section than the pass-through cross-section so that the first clamp end can be inserted in the first ring, the second clamp end presenting a second section that is larger than the first cross-section, the first clamp end defining a through hole designed to receive a rope able to support a user, the through hole having a second pass-through cross-section, the second end of the wire-like element being fixed to the clamp via a first attachment point located between the through hole and the second clamp end, the clamp being a part that is more rigid than the wire-like element;
• a cord having a first cord end fixed to the clamp via a second attachment point and a second cord end having a second ring, the second ring defining a third pass-through cross-section that is smaller than the second pass-through cross-section.
