A device for closing sequence control in a double-leaf door, having an active leaf and a passive leaf, wherein both door leaves (2, 3) are each connected via a door hinge (5a, 5b) to a wall region adjoining the door wings (2, 3) so they are pivotable about a stationary bearing rotational axis (L, L'), comprising: - a blocking unit, using which the active leaf is fixable in a minimum opening position in the door closing direction, - a trigger unit, which is controlled by the passive leaf, and which triggers the blocking unit at a predefined position of the passive leaf, - a slide rail door closer, which is arranged between the active leaf and the wall region, and which comprises a slide rail and a slider guided linearly therein, having a closing arm acting on the active leaf, the slide rail door closer being installed on the side of the active leaf opposite to the door hinge and applying a closing force to the closing arm, and the closing arm being linked at its first end region to the door closer so it is rotatable about a door closer rotational axis and being mounted at its second end region on the slider so it is rotatable about a guide rotational axis, - the bearing rotational axis, the door closer rotational axis, and the guide axis being arranged, in the case of a projection in the plane orthogonal to the axial direction of the bearing rotational axis, in such a manner that, together with the two regions (B1, B2) located in between, they overall form a toggle lever, the stationary linkage point of which is the bearing rotational axis, and the further pivot points of which are formed by the door closer rotational axis and the guide axis, characterized in that the blocking unit comprises a locking lever (17, 30, 33), which is linked on or in the slide rail, the locking lever linking the toggle lever to transmit a locking force from the blocking unit to the toggle lever between the two outer pivot points of the toggle lever in the projection plane, preferably in the region of the closing arm, or at the pivot point of the guide rotational axis. - a blocking unit, using which the active leaf is fixable in a minimum opening position in the door closing direction, - a trigger unit, which is controlled by the passive leaf, and which triggers the blocking unit at a predefined position of the passive leaf, - a slide rail door closer, which is arranged between the active leaf and the wall region, and which comprises a slide rail and a slider guided linearly therein, having a closing arm acting on the active leaf, the slide rail door closer being installed on the side of the active leaf opposite to the door hinge and applying a closing force to the closing arm, and the closing arm being linked at its first end region to the door closer so it is rotatable about a door closer rotational axis and being mounted at its second end region on the slider so it is rotatable about a guide rotational axis, - the bearing rotational axis, the door closer rotational axis, and the guide axis being arranged, in the case of a projection in the plane orthogonal to the axial direction of the bearing rotational axis, in such a manner that, together with the two regions (B1, B2) located in between, they overall form a toggle lever, the stationary linkage point of which is the bearing rotational axis, and the further pivot points of which are formed by the door closer rotational axis and the guide axis,
