The invention relates to a device for synchronization of locking devices of a plurality of furniture (1, 2, 3) in adjacent positioning. Each piece of furniture (1, 2, 3) comprises at least one furniture part (13, 23, 33) capable of being pulled out from the furniture body of the furniture, at least one locking bar (14, 17, 24, 34) is arranged at a furniture body for locking the at least one furniture part (13, 23, 33), each locking bar (14, 17, 24, 34) is in an operational connection with a corresponding locking element (15, 18, 25, 35) arranged at the furniture body. The locking elements (15, 18, 25, 35) are movable between two positions in which the locking bars (14, 17, 24, 34) are released and locked, respectively. The locking elements (15, 18, 25, 35) are movable by displacement of the locking bars (14, 17, 24, 34) from a released position into a locked position via movement of the locking bars (14, 17, 24, 34).
