Abstract: A holding device for vertically positioning a windshield or rear window so that it can be bonded into the frame of a motor vehicle. It has a holding part which can be inserted into a lower transverse part of the frame and a series of support steps transversely spaced from one another in a direction parallel to the transverse part of the frame and pivotally connected to the holding part so that they can individually and elastically pivot out to a holding position or be pressed into an out-of-the way position. The steps each have a support face, the faces being arranged in step wise fashion at an equal vertical distance from each other.
