Rope anchoring device, comprising a pair of plates (1a), facing parallelly to each other, a cuneiform holding body (2) adapted to be inserted between the pair of plates (1a) and comprising a shaped edge suitable to house a rope (3) wound on it, at least a pair of retaining elements (1d) inserted between the plates (1a) and arranged so as to allow the insertion of the cuneiform holding body (2) between them, to exert a retaining force on a rope interposed between the shaped edge and the retaining elements (1d); the anchoring device comprises two respective pairs of elongated slits (1f) each one of the retaining elements (1d) being inserted in a respective of the pairs of elongated slits (1f) that are configured to constrain the retaining elements (1d) to exert the gripping force; the coupling, between the retaining elements (1d) and the pair of elongated slits (1f), is adapted to allow movements at least in a longitudinal direction of the retaining element (1d), to exert the gripping force on the rope in a uniform manner.
