ABSTRACT OF THE DISCLOSURE A corner joint for lattice-type structures is disclosed. The joint comprises at least two connecting elements adjustable angularly in relation to each other about a common axis, and each having a hub and a sleeve-like holder, extending radially of the axis of the hub, for a lattice element. The hubs of the con- necting elements are provided with uniformly divided internal tooth profiles and a locking piece is adapted to be inserted into the hubs of the connecting elements constituting the corner joint, the locking piece having external teeth matching the internal tooth profile of the hubs. The end faces, facing each other, of adjacent connecting elements are provided with teeth suitable for mutual engagement, without play, and having the same pitch as the internal teeth in the hubs, so that the assembled connecting elements can be secured in a specific angular setting without the locking piece.
