The invention concerns a prosthesis (2) designed to be inserted between two neighboring vertebrae, comprising a core (4) made of an elastic material and covered, over part of its periphery, with a rigid material coating (6) designed to be in contact with the two neighboring vertebrae. The core (4) comprises, in transverse cross-section, two end portions (8) linked by a median portion (12) and said coating includes two caps provided with a threading and covering at least partially the external periphery of the end portions (8), the distance separating the caps increasing towards the prosthesis front part.
