Abstract: Connecting elements (4) can be inserted into the ends of the individual bar-shaped elements (2), the connecting elements having a projection (13) which engages into an opening (8) at the end of the tube. In that way each individual connecting element (4) can be released even in a framework construction which has already been assembled. The bar-shaped elements (2) are exchangeable and the framework can be broken down into all individual parts.

Abstract: Mountings for detachably connecting juxtaposed edges of at least two wall panels that radiate from the mounting are described wherein a jaw member is formed with two jaw surfaces that engage faces of the panels on one side of the panels close to the edges. The two jaw surfaces are spaced apart and an intermediate part either formed in one piece with the jaw member or fixed thereto, is located between the jaw surfaces and between the edges of the panels. The panels are maintained in contact with the jaw surfaces by two further such surfaces on a jaw device engaging faces on the opposite side of the panels. This jaw device is formed with a recess that fits onto the intermediate part and determines the extent of separation of the opposed jaw surfaces. At least one screw fixes the jaw device to the intermediate part. The location of the jaw surfaces determines the angle at which the panels are set relatively to one another.
