1. An apparatus for controlling the movement of two guide units, each of the two guide units comprising a fixed rail and a movement rail which can be displaced relative to the fixed rail, wherein the apparatus comprises:
a first ejection unit and a second ejection unit, each of which can be arranged on a respective one of the two guide units and which are spaced apart from each other; and
a synchronization device having a connection element,
wherein the connection element is a separate component connecting the first ejection unit and the second ejection unit to each other to synchronize the first and second ejection units, wherein the first and second ejection units are configured in an identical manner,
wherein each of the first and second ejection units has an adapter member, on which a respective end portion of the respective connection element can be releasably fitted,
wherein the adapter member includes a receiving portion having a receiving volume in which the fitted end portion of the connection element is accommodated in a fixed position relative to the adapter member,
wherein the receiving volume accommodating the fitted end portion of the connection element is surrounded over a partial circumference with respect to a longitudinal axis of the end portion of the connection element by a fixed wall of the adapter member and a closure portion of the adapter member is provided over a remaining circumferential portion with respect to the partial circumference,
wherein the fitted end portion of the connection element moves into abutment with the fixed wall, and
wherein the closure portion is pivotably articulated to the adapter member and pivotable from an open position of the closure portion on the adapter member, in which the receiving volume is open over the remaining circumferential portion for introducing the end portion of the connection element, reversibly into a secured closure position of the closure portion, wherein in the secured closure position of the closure portion, the remaining circumferential portion is closed.
