A method for attaching at least one transverse anchorage element to an armor element intended to be housed in an end-fitting of a flexible pipe, including the following steps: the supply of an attachment device accepting an anchorage element; the bringing of an opening to face the armor element; the melting of one end of the anchorage element facing the armor element and of a region of the armor element facing the anchorage element, inside the cavity of the attachment device; the forging of the anchorage element transversely on the armor element, using the attachment device; and the formation of a weld connecting the anchorage element and the armor element.
