in diameter thereby making flat prefabricated elements 2 and or transverse insert 9 fragile because of their generally long length essentially of the order of double the width of the flat prefabricated elements 2 in the case of diagonal guiding means 10 the rigid guiding means 10 may be flexible to a certain extent advantageously given them the ability to deform to a certain extent for connection between the two flat prefabricated elements 2 and for their constituent elements this freedom to deform obtained regardless of the type of guiding means used represents an important feature of the invention among other things it allows the formation of a deformable articulation between the flat prefabricated elements 2 as indicated previously and it also allows expansion or contraction with temperature changes and flexion without breaking when stress is exerted on flat prefabricated elements 2 the connecting system 1 thus endures and u201c lives u201d along with the flat prefabricated elements 2 which it is used to assemble other guiding means besides connectors are possible for example using a handle a lever or an exterior tool a connection is then formed in some way resulting in slight compression of the insert maintaining the insert results in blocking which locks the assembly the connection may be rigid or flexible with extremities immobilized by pins a preferred method of utilizing a connection system 1 will now be described in detail with reference to fig1 through 8 the example describes a connection system 1 comprising a hexagonal transverse insert 9 two tie beams 23 constituting the guiding means 10 in the form.
