The invention relates to an intervertebral implant comprising: a spacer (12); a braid (14) for fixing said spacer between the spinous processes of two adjacent vertebrae; and a clamping device for clamping said braid. The clamping device comprises: a fixed part (28) constituted by a portion of said spacer (12) and defining at least one first clamping surface for clamping said braid; a mobile assembly (28) movable relative to said spacer (12) and defining at least one second clamping surface for clamping said braid; and displacement means for moving said moving assembly (30) relative to said fixed part (28) to displace said mobile assembly between a first position in which said first and second clamping surfaces face each other but are apart to define a free passage for a portion of the braid (14), and a second position in which said first and second clamping surfaces are moved towards each other to clamp said portion of braid (14).

L'invention concerne un implant intervertébral qui comprend : un espaceur (12) ; une tresse (14) destinée à attacher ledit espaceur entre les apophyses épineuses de deux vertèbres adjacentes ; et un dispositif de clampage destiné à clamper ladite tresse. Le dispositif de clampage comprend : une partie fixe (28) constituée par une partie dudit espaceur (12) et définissant au moins une première surface de clampage pour le clampage de ladite tresse ; un ensemble mobile (28) déplaçable par rapport audit espaceur (12) et définissant au moins une seconde surface de clampage pour le clampage de ladite tresse ; et des moyens de déplacement destinés à déplacer ledit ensemble mobile (30) par rapport à ladite partie fixe (28) afin de déplacer ledit ensemble mobile entre une première position à laquelle lesdites première et seconde surfaces de clampage sont face à face mais espacées pour définir un passage libre pour une partie de la tresse (14) et une seconde position à laquelle lesdites première et seconde surfaces de clampage sont déplacées l'une vers l'autre pour clamper ladite partie de tresse (14).
