A quick-change device for automatically changing an attachment on a construction machine includes first receptacles disposed on one side of a support for receiving a first coupling element; second receptacles disposed on the other side of the support for receiving a second coupling element, with the second receptacles having at least one locking element which moves between a release position for coupling or uncoupling the attachment and a locked position for holding the attachment in place on the quick-change device; and a display device disposed on the support for monitoring the lock status. The display device includes an electrical lock status indicator and an electrical control unit which activates the lock status indicator in an extended locked position of the locking element and deactivates it in a retracted release position and an extended position of the locking element different from the locked position.
