A metal wire anchor for protection system against rockfalls and avalanches, comprising a length (1) of metal wire cable bent to form a loop (10) at leat partially encased by a metal sheath (2), and a portion to be secured to the ground. The metal sheath (2) is directly in contact with the cable (1) and provides a central portion (3) having a first thickness ( ELEMENT 1), and two end portions (4,5) having a second thickness ( ELEMENT 2) smaller than the former. The two end portions (4,5) are connected by two joining sections (6,7) having a progressively decreasing thickness, the portion (3) with said first thickness ( ELEMENT 1) extending over the whole loop (10), while the end portions (4,5) having said second thickness ( ELEMENT 2) extend along the cable sections that are parallel. <IMAGE> |
