A hoisting device includes a body, a hoisting rope, a rope drum arranged in connection with the body, on which a first end of the hoisting rope is fastened, and a hoisting part which ascends and descends by means of the hoisting rope. The hoisting device includes a fastening device of a second end of the hoisting rope, which is formed into a loop wherein a spiral groove is substantially surrounding the entire loop and in which the part adjacent to the second end of the hoisting rope is received. The hoisting device further has a fastening arrangement which locks the second end of the hoisting rope to the fastening device, preventing the second end from being pulled out of the fastening device.
