ABSTRACT OF THE DISCLOSURE A device for coupling together laterally directed scaffold elements and uprights in a scaffold or the like. Each coupling device includes an engagement member which is connected to the upright and is open upwards at least in the position of use. Said member is provided with a wall which extends with spacing from the upright and which delimits a space situated between the upright and the wall. A hook-up member is situated at least at one end of each scaffold element and is adapted to hook into the engagement member. A first clamping member is movable in relation to the scaffold element and is adapted to bear against the upright and against the engagement member. A second clamping member is adapted, in a locking position to be forcibly gripped between the respective first clamping member and the respective scaffold element. The clamping member is pressed towards the upright and the scaffold element is pressed in the direction out from the upright and as a result is clamped by means of the hook up member in the engagement member. The second clamping member can consist of two differently shaped wedges which enable adjustment between different transverse directions of the uprights. The invention produces an improved strength of the coupling.
