A setting gripper (16) is disclosed for an anchor device of the type comprising two co-axial components of which each has a head with the head being spread apart co-axially during setting. The gripper (16) includes two jaws (36, 49) which are engaged between the two heads and are spread apart by a pivoting lever (20) relative to a gripper body (19) around axes (95, 111, 82, 85) which are increasingly removed from a zone of mutual contact (64, 110) between the lever (20) and a slider (21). The slider (21) defines one (49) of the two jaws, whereas the other jaw (36) is defined by the gripper body (19).
