A connecting portion is provided between the drive unit and the sluice. The drive unit is cooperating with the middle-tube and the connecting portion where the drive unit is operated the middle-tube is displaced in the distal direction and the actuating unit together with the outer-tube attached thereto is displaced in the proximal direction. The inner-tube is cooperating with the middle-tube and/or the connecting portion and/or the drive unit in such a way that the inner-tube is displaced at least to some extent relative to the actuating unit.
