A locking device for locking two ties which may be coupled to an intervertebral spacer. The locking device includes a body having a first face for facing a wall of the intervertebral spacer, and a second face opposite the first face. The body includes an axial slot opening out into both faces of the body; two lateral slots, each lateral slot opening out into both faces and having dimensions suitable for allowing one tie to pass freely therethrough between opposing side surfaces of the lateral slot; and two presser surfaces defined in the first face, each presser surface extending between one end of the body and the nearer lateral slot. One side surface of each lateral slot converges with the associated presser surface to define a first edge, and the other side surface of each lateral slot converges with the second face to define a second edge.
