A fastener for joining a pair of elements comprises a fastener member having an elongated stem provided at one end with an enlarged head and formed spaced from this head with a transversely throughgoing passage. This fastener member is insertable through aligned holes in the elements to be joined with the head bearing on one of the elements and the passage exposed at the other of the elements. A plastically deformable elongated wedge is driven through the passage so that its intermediate portion lies in the passage and its end portions lie on either side of the stem. One longitudinal edge of this wedge bears in one direction on the other element and another longitudinal edge bears in the opposite direction on the stem in the passage. After being driven in, the end portions of the wedge are bent over to lock the assembly tightly together.
