A spring balance has top (1) and bottom (2) supports that are moved against each other towards the force of a compression spring (5). The top and bottom supports can be inserted between the upper edge of a motor vehicle's window and a seal that works together with this upper edge. Bolts (4) each have a head (7) on the underside of the bottom support.
