The object of the invention is to join together two plates 1 and 1' which are arranged parallel to one another to form a hollow 2 which will be filled with concrete, a wall being formed after setting of the latter and removal of the plates 1 and 1'. The connecting- together of these plates 1 and 1' in order to form the hollow 2 and to be able to retain the concrete which is to constitute the wall is achieved by means of a stud 3 on which are wedged two small blocks of cement 4 located on the inner face of the plates 1 and 1', another two small blocks of wood 5 which are located on the outer face of said plates, and said corresponding external tightening nuts 7. The elements which form this joining assembly can be recovered, with the exception of the small cement blocks 4 which remain, forming part of the wall. <IMAGE>
