Claim:
A device to establish a connection between two adjacent slabs, said device comprising: first and second modules derived from sheets, each of the modules comprising: a series of flat first elements, which have projections, aligned in the same plane, a series of second elements in the form of a right angle, each of said second elements comprising a first flat part, which is in the same plane as said projections and which is integral with one of said projections, and a raised second flat part, which forms a right angle with said first part, and with said projection, flat third elements, which are in the same plane as said raised parts and which form connections in the form of first longitudinal members between said raised parts, said first module disposed adjacent to said second module with the raised parts of the first and second module facing each other along the two sides of a center plane and the longitudinal members of the first and second module equally facing each other along the two sides of said same center plane, and the projections of each module mesh together and extend on both sides of said center plane.
