Abstract: An intervertebral linking device of the type comprising bone anchoring elements to be interconnected by at least one intervertebral linking rod. The intervertebral linking device includes a the fixing system mounted on a connection bar the fixing system including at least one sliding displacement of the fixing system associated with a locking nut to lock said system in a fixed position. The connection bar is mounted on each anchoring element a guiding collar in rotation around an axis of the connection bar and locking the connection bar in a fixed specific position.

Abstract: Flexible fastening device designed to interlock a longitudinal element (1) and an osseous anchor device (2), either internal, in particular vertebral, or external, the anchor device (2) comprising an intra-osseous part and an extra-osseous part (20) associated to a tightening device (21), the fastening device (10) comprising a first connection part (13a) and a second connection part (13b) designed to receive the extra-osseous part (20) of the anchor device (2), and an intermediate part (12a, 12b) joining the first and second connection parts (13a, 13b) and designed to encircle tightly the longitudinal element (1), the flexible fastening device (10) comprising a strand (11) out of elastic material or of material in the process of phase transformation, and the intermediate part (12a, 12b) comprising at least one spiral coil (12a, 12b) adapted to encircle the longitudinal element (1), so that a bringing closer of the first and second connection parts (13a, 13b) by the tightening device (21) or by the effect of t
