Claim:
An intervertebral disk prosthesis comprising: a first assembly comprising a prosthetic plate having a fastener face provided with anchor members for anchoring in a vertebra; and a second assembly comprising a prosthetic plate having a fastener face provided with anchor members for anchoring in another vertebra; wherein each anchor member comprises: a slot formed in a prosthetic plate and passing right through it; an anchor element mounted on said slot, said anchor element having at least a portion of size greater than the height of said slot; a means for forming a pivot axis XX′ for pivoting said anchor element relative to the prosthetic plate, whereby said anchor element can be moved from a rest, first position in which said anchor element does not project from the fastener face of the prosthetic plate, towards an active, second position in which at least a portion of said anchor element projects from the fastener face of the prosthetic plate; a first holder means for holding in said first position; and a second holder means for holding in said second position, wherein the anchor element has a second end having said first and second holder means, and a first end shaped to co-operate with a portion of the wall of said slot to define said means forming the pivot axis XX′, wherein the second end of the anchor element has a first portion suitable for co-operating by wedging with a second portion of the wall of said slot opposite from the portion defining the means forming the pivot axis and forming said first holder means, and a second portion that is elastically deformable defining a recess suitable for co-operating with said second portion of the wall of the slot to form the second holder means.
