The invention relates to a crimping tool having crimping indenters (7), wherein the crimping indenters (7) are arranged in a star shape directed at a crimping region and are subjected to rotational action radially outwards for the crimping movement by means of an actuating part, wherein the crimping indenters are further mounted about an axis of rotation (8) transversely to the longitudinal extent thereof for pivoting-in and form an abutment region (9) on the crimping region side of the axis of rotation (8). In order to specify a crimping tool in the case of which, as far as possible, no gaps are formed between the crimping indenters during crimping, the invention proposes that a radial movement and/or circumferential movement is brought about to coincide with the rotational action on the crimping indenters (7), in order to obtain abutment of a crimping indenter (7) in the abutment region (9) thereof against the counter-abutment region (10) of a crimping indenter (7) adjacent to the crimping indenter (7) in the pivoting direction or counter-pivoting direction.
