Disclosed is an instrument for inserting a multipart intervertebral endoprosthesis (9) comprising two endplates (91, 92) and a sliding core (93) that is disposed therebetween. Said instrument encompasses a handle part (21, 31), gripping members for retaining the endplates therebetween, and a force-transducing part for applying an insertion force to the intervertebral endoprosthesis (9). The gripping members can be moved back and forth relative to each other and be clamped against the intervertebral endoprosthesis (9) via a joint (4). Protrusions (51, 52) that extend in the clamping direction (12) or recesses are embodied on the gripping members for positively retaining the intervertebral endoprosthesis (9). A block (61) comprising a stop area (62) is provided, which is guided in the direction of the longitudinal axis (10), can be moved by means of an actuating device (7) so as to rest against the intervertebral endoprosthesis (9), and fixes the intervertebral endoprosthesis (9) relative to the protrusions (51, 52) or recesses in the forward position thereof.
