ABSTRACT:
A device for making a connection between concrete slabs, the device having two modules derived from sheets, each module having a number of flat elements which form projections, each module further having elements in the form of a right angle, having a flat part integral with projection, and a raised part, and longitudinal members between the raised parts, and wherein the modules are assembled in such a way that the raised parts and longitudinal members of the two modules are facing each other along the two sides of a center plane, and that the projections extend on both sides of the center plane, so as to form meshing projections which pass from one side of the joint to the other.
