Clamping device according to patent claim 2, wherein the first and second guiding means (51, 52) consist of, according to the described order, the first finger and the second finger (511, 521) which cooperate accordingly with the first, respectively, second gear (512, 522). 4. Clamping device according to patent claim 3, wherein the first finger (511) is placed on the flange (3) and the body (1) is transmitted by means of the first gear (512). 5. Clamping device according to patent claim 4, wherein said first gear (512) includes a first part (5121), wherein the first finger (511) is located when the flange (3) is in the clamping position, and which is parallel to the direction ( S) clamping, and the second part (5122) which is oriented towards the crane (2). 6. Clamping device according to patent claim 3, wherein the second finger (521) is placed on the body (1) and the second gear (522) is transmitted via the flange (3) by spreading evenly so that it is flat and in the direction (S) of clamping when the flange (3) is in the clamping position. 7. Clamping device according to patent claim 1, wherein the transmission device (4) consists of a transmission finger (42) and a transmission gear (401) that cooperate with each other. 8. Clamping device according to patent claim 7, wherein the slide (20) contains feet (40) of a flattened shape, the transmission gear (401) which is transported via the foot (40) of the slide (20), wherein the flange (3) it contains a flange groove (3) in which the foot (40) continues and slides, the transfer gear (401) being threaded through by means of a pin (42) to form a transfer finger (42). 9. Clamping device according to patent claim 7, wherein the transfer gear (401) consists of a first part (4011) inclined in relation to the axis of the slide (A), and a second part (4012) predominantly perpendicular to the axis of the slide (A) and wherein this transfer finger (42) is located when the flange (3) is in the release position. 10. Clamping device according to patent claim 1, wherein the body (1) consists of a clamping jaw (11) and this clamping jaw contains two wings (110) parallel to each other, the flange (3) is moved between the wings (110). 11. Clamping device according to claim 1, characterized in that it contains first support elements (6) and second support elements (7), and wherein the first support elements (6) include a first fixed support element (61) in relation to the body (1) and a first movable support element (62) connected to the flange (3), wherein these first fixed and movable support elements (61, 62) selectively cooperate, at least at the end of the stroke of the flange (3) towards its clamping position, in order to could get sliding contact with each other parallel to the direction (S) of clamping, and the other supporting elements (7) include the second supporting element (71) in relation to the body (1) and the second movable supporting element (72) connected to the flange (3), these other fixed and movable supporting elements (71, 72) selectively cooperate, at least at the end of the flange (3) stroke towards its clamping position, to be in contact with each other by sliding movement parallel to the clamping direction (S), the first and second supporting elements (6 , 7) are spaced apart from each other to enable carrying at edges (3) on part (P) for clamping with a clamp. 12. Clamping device according to patent claims 10 and 11 taken in combination, wherein the first fixed support consists of the bearing surface (61) of the body (1) between the wings (110) of the clamping jaw (11), the first movable bearing element is located in to the first claw (62) of the flange (3). 13. Clamping device according to patent claims 10 and 11 taken in combination, wherein the second movable supporting element (72) consists of two other supporting bases (721) carried by the flange (3) and extending symmetrically on the other side of the middle plane ( M) of the flange (3) and the slide (20), transverse to the axis of rotation, and wherein the second fixed supporting element (71) consists of two supporting grooves (711) of the body (1) made in the wings (110) opposite each other, on which on the sides, the other support bases (721) bear symmetrically against the mentioned middle plane in relation to it. 14. Clamping device according to patent claim 1, wherein the slider (20) is transmitted by means of a rod (202) and a piston (201) made integrally over the assembly, and the rod (202) is connected to the transmission means (4). 15. Clamping device according to one of the preceding patent claims, wherein the body includes a fastening front side predominantly perpendicular to the clamping direction.
