A block is inserted in the corner and a joining surface of the block and the elements to be joined is provided with intermeshing tongues and grooves preferably of the finger-type form in their longitudinal direction a segment of a circle about an axis perpendicular to the plane of the joint elements. The matching fingers are glued together. The joint of this invention may be used for instance in a lattice girder and especially in frames for furniture. Further by a simple provision it will be possible to obtain a three-dimensional joint by adding a third element extending in the direction perpendicular to the plane of said two elements.
