Abstract: An apparatus for controlling the movement of two guide units having a first and second ejection units, including a synchronization device having a connection element which connects together and synchronizes the first and second ejection units. Each ejection unit has an adapter member that provides a receiving portion having a receiving volume in which the end portion of the connection element can be accommodated. The receiving volume is surrounded over a partial circumference by a fixed wall of the adapter member, and over a remaining circumferential portion with respect to the partial circumference a closure portion of the adapter member is provided. The closure portion is pivotably articulated to the adapter member and can be pivoted from an open position reversibly into a secured closure position of the closure portion, wherein in the closure position of the closure portion the remaining circumferential portion is closed.
