A locking device for a telescopic boom, in particular of a mobile crane, has an actuator for generating an actuating force, a driver that is reversibly coupled, during a telescoping movement of the telescopic boom, to a locking bolt, which is secured at a boom extension segment of the telescopic boom, and to be moved under the action of the actuating force for adjusting the locking bolt between at least one locking position and a release position. A driver bolt can be moved reversibly by the actuating force between a carry-along position gripping an inner boom extension segment and an empty running position not gripping a boom extension segment. A slotted actuating link is configured for a joint movement of the locking bolt and the driver bolt. A movement plane of the slotted actuating link is oriented perpendicularly to the telescoping direction of the telescopic boom.
