<p>The frame is for horticultural purposes such as tying up flowers or shrubs. It consists of columns which can be inserted into the soil, with connected transverse and longitudinal bar supports which are releasably joined together by sheath-type connecting pieces. There are also clamping devices to clamp the connecting pieces rigidly to the inserted bars. The clamping device has two wedges (5, 6) which are inserted at opposite ends into the correcting piece (1). The wedges are tensioned by a spring element (g) in the clamping position.</p> |
