The invention relates to a synchronization device for moving a first actuating device in synchronization with at least one second actuating device. The first actuating device and the second actuating device are provided on a piece of furniture in the installed state in order to move a movable furniture part. The device includes a synchronization rod for transferring a synchronous motion of the at least two actuating devices, and at least one fastening device, by which the synchronization rod can be detachably connected to at least one of the two actuating devices. At least one detachable locking device is also provided, which prevents the synchronization rod from being connected to the at least one fastening device in the locked state of the locking device, wherein the locking device is in the locking state without prior actuation by a user.
