In a fastener to join two timbers, there is a concealed coupling bar extending on both sides of the contact area into the timbers and linked to them by two components placed perpendicularly through its extremities. In this invention, one at least of these components is capable of expanding in order to compress the joint, and is actuated perpendicularly to the coupling member.
