Abrégé

Described is an anchor (10) for systems for protection against falling masses, comprising a portion (21) of an anchoring cable (20) designed to form at least one anchoring loop (30), a protective sheath (40) wrapped around the portion (21) of the cable (20), at least one containment collar (50) such as to transversely wrap around the sheath (40) and the anchoring cable (20) in the vicinity of the anchoring loop (30), a mechanical protection element (60) designed to be positioned between the anchoring cable (20) and fixing means in such a way as to evenly distribute the stresses between the fixing means and the cable (20) in an operating condition of the anchor (10). The mechanical protection element (60) is an annular element which has a housing portion (61) formed by an annular groove (62) positioned along a perimetric surface (63) of the annular element (60) and designed to at least partly house the portion (21) of the anchoring cable (20) and a constraining portion (64) which has a through hole (65) designed to house the fixing means.

Abrégé

Described is a mesh (1) made of wire rings, wherein each ring (2) is made by repeatedly winding and twisting a wire (3) over itself to form an annular strand from which protrude the two ends (4, 5) of the wire (3); the two ends (4, 5) of the wire (3) being moved near to one another and being simultaneously helically wound around the strand with the same direction of winding to close the strand.
