4. An element according to any of claims 1 to 3, characterized in that it comprises a rectangular plane plate (32) fixed by welding on the first piece (18) and substantially vertically arranged in the area ofthis piece (18) which is embedded in the concrete in the proximity to the piece face (9) forming the above-mentioned shoulder, the dimension of said plate (32) when considered in a parallel direction to the rail being preferably higher than the corresponding dimension of the piece, portions of this plate which are in projection with respect to the piece being substantially equal and each having, from the vertical faces which are perpendicular to the rail, a semi-circular recess (34) for allowing a concrete iron rod to pass.
5. An element according to claim 4, characterized in that the plate (32) is fixed on the face of the piece (18), which is intended to be turned towards to rail.
6. An element according to claim 5, characterized in that the plate (32) is shaped in order to present a flange (49) which extends in a perpendicular direction to the face (9) of the piece (18), forming the rail shoulder, the face (50) of this flange, which is turned towards the socket (12) being located at the same level as above-mentioned faces (47) of the portions (31) of the plate (28).
7. An element according to any of claims 1 to 6, characterized in that the dimensions of both pieces (18 and 19), when considered in a parallel direction to the rail (2), are equal.
8. An element according to any of claims 1 to 7, characterized in that the lateral faces of the flat bars used for both pieces (18 and 19) are plane and parallel by pair, two contiguous lateral faces forming a right angle, at least the flat bar forming the first piece (18) having, from its lateral face intended to form the end of the anchoring lug (7), either one cutting-out (22) which is symmetrical about the flat bar axis perpendicular to said lateral face, and which is intended to form a central recess in the anchoring lug (7) of said piece (18) so as to allow passage of at least one connecting means (24) of two concrete blocks forming a sleeper (4), or two cuttings-out (22 which are symmetrical about the above-mentioned axis and are intended to form on both sides of a central anchoring lug portion (25), recesses allowing passage of concrete iron rods of a one-piece sleeper (4) made of prestressed concreted.
