The invention concerns a prosthesis (2) designed to be inserted between two neighbouring 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 neighbouring 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 (6) provided with a threading and covering respectively at least partially the external periphery of said end portions (8), the distance separating said caps increasing towards the prosthesis front part. Said prosthesis can easily be inserted and has excellent stability inside the intervertebral space.
