Abstract
A cold frame is formed with lateral wall elements containing transparent hollow chamber panels, and supports which are provided with lateral flanges. The lateral wall elements include lateral edge areas provided with through-passages and formed by the hollow chamber panels thereof, and rest against the flanges of the supports. The lateral wall elements are connected to the supports by clamping devices. The clamping devices include clamping elements which rest against the inner sides of the hollow cavity panels forming the edge areas of the lateral wall elements and are clamped between the hollow cavity panels and the tops of positioning bars belonging to the clamping devices. The bars protrude from the through-passages of the hollow chamber panels and they are rigidly connected to the flanges of the supports.
