A device (10) for actuating levers (9) for locking containers in the receptacles (3) of the output star conveyor (1) in a labeling machine. For each receptacle (3) there is a support (12) for a shaft (11) which is connected at its outer end to one of the levers (9) and at its inner end to a block (13) that has an eccentric protrusion (13a). According to the invention, there is an abutment (14) which is provided with at least one tab which is adapted to selectively assume, as a consequence of rotation commanded by adapted means which can be programmed, a first position of interference with the eccentric protrusion (13a) of at least one block (13) that arrives at the device (10), so as to cause the rotation of the corresponding locking lever (9) from a neutral position to an active position in which it locks the container that is present in the corresponding receptacle (3), and a second position, in which no tab interferes with one of said eccentric protrusions (13a).
