The invention relates to a device for implanting in a human or animal vertebral column, said device comprising a base carrier (10) that can be fixed to a first vertebral body, an upper carrier (14) that can be fixed to a second vertebral body, and a spacer element fixed between the base carrier and the upper carrier. The base carrier (10) and/or the upper carrier (14) are provided with a cavity (18, 24) comprising undercuts, for receiving the spacer element in a positively locked manner. The aim of the invention is to economically create one such device that ensures complete freedom of movement of the vertebral column. To this end, the spacer element is embodied as metallic bellows (12).
