Socket for fixing a concrete slab, of the type comprising an axial bolthole 14 leaving an end 2 which is intended to be flush with the interior face of the slab serving to fix it and, at the other end, a means of anchoring the socket to the reinforcement of the concrete, characterised in that the anchoring means is constituted by the combination of an entry recess 4, leaving the opposing end 3 and whose mean plane contains the axis 5 of the socket, and of two locking recesses 10 whose mean plane is substantially perpendicular to the axis 5, each of these locking recesses 10 being made in one of the end portions 9 of the body 1 of the socket and separated by the entry recess 4, and in opposite directions in order to ensure the locking by rotation in the same direction of the socket 1 to a reinforcement bar after insertion of the latter into the entry recess 4. <IMAGE>
