Abstract: 1. A monobloc sealing device comprising a piece of wire cable for disposing therein one end of a piece of a wire cable and a stopper and a through bore which is in communication with the stopper and serves for passing a free end of the wire cable the stopper is designed as spring-loaded bodies of rotation having different diameter adapted to interact with the free end of a wire cable, characterized in that the diameters of bodies of rotation are selected so that the doubled angle between the line connecting centers of cross-sections of rotation bodies being in operable state and the longitudinal axis of the bore for the stopper is not greater than the angle of wire cable wedging. 2. The monobloc sealing device according to claim 1, characterized in that the bore is plugged from the end for passing the free end of a wire cable the plug is made of a high-strength material in the form of a sleeve in which a spring is positioned, the plug is adapted for displacement along the bore longitudinal axis at a different distance from the body end surface. 3. The monobloc sealing device according to any one of to claims 1-2, characterized in that co-axial cross grooves are provided in the device body from the end for passing the free end of a wire cable, the longitudinal axes of said grooves and bores intersect, and the width and the depth of the grooves exceed the wire cable diameter. 4. The monobloc sealing device according to any one of to claims 1-3, characterized in that the end surface of the body between bores for the cable from the side of inserting the free end is concave with a radius of curvature constituting at least half distance between longitudinal axes of bores for a wire cable and not exceeding the groove's depth. 5. The monobloc sealing device according to any one of to claims 1-4, characterized in that the bodies of rotation are made as balls. 6. The monobloc sealing device according to claim 5, characterized in that the balls are made of steel not subjected to strengthening and have rough surface. 7. The monobloc sealing device according to any one of to claims 1-6, characterized in that the diameter of a smaller ball is greater than the diameter of the through bore for accomodating the cable free end, while the diameter of the other ball equals to the diameter of the bore for the stopper. 8. The monobloc sealing device according to any one of to claims 1-7, characterized in that one end of the wire cable is rigidly fixed in the bore by means of plastic deformation in the cable area. 9. A monobloc sealing device comprising a piece of wire cable for disposing therein one end of a piece of a wire cable and a stopper and a through bore which is in communication with the stopper and serves for passing a free end of the wire cable the stopper is designed as spring-loaded bodies of rotation having different diameter adapted to interact with the free end of a wire cable, characterized in that a compensator installed between the stoppers. 10. The monobloc sealing device according to claim 9, characterized in that the bodies of rotation are made as balls. 11. The monobloc sealing device according to any one of to claims 9-10, characterized in that the compensator is made as a cylindrical or conical spring. 12. The monobloc sealing device according to any one of to claims 9-11, characterized in that the bore is plugged from the end for passing the free end of a wire cable the plug is made of a high-strength material in the form of a sleeve in which a spring is positioned, the plug is adapted for displacement along the bore longitudinal axis at a different distance from the body end surface. 13. The monobloc sealing device according to any one of to claims 9-12, characterized in that co-axial cross grooves are provided in the device body from the end for passing the free end of a wire cable, the longitudinal axes of said grooves and bores intersect, and the width and the depth of the grooves exceed the wire cable diameter. 14. The monobloc sealing device according to any one of to claims 9-13, characterized in that the end surface of the body between bores for the cable from the side of inserting the free end is concave with a radius of curvature constituting at least half distance between longitudinal axes of bores for a wire cable and not exceeding the groove's depth. 15. The monobloc sealing device according to any one of to claims 9-14, characterized in that the balls are made of steel not subjected to strengthening and have rough surface. 16. The monobloc sealing device according to claim 15, characterized in that the diameter of a smaller ball is greater than the diameter of the through bore for accomodating the cable free end, while the diameter of the other ball equals to the diameter of the bore for the stopper. 17. The monobloc sealing device according to any one of to claims 9-16, characterized in that one end of the wire cable is rigidly fixed in the bore by means of plastic deformation.
