The object of the invention is a releasing method and a releasing member for releasing a towed device from a cableway at a desired point without an assisting person or without stopping the lift. According to the method a towing member ( 2 ) connected to the towing rope ( 10 ) of the towing apparatus ( 5 ) of the cableway ( 4 ) is released from the clutch member ( 1 ) in the towed device by changing the vertical towing angle (R) between the towing member ( 2 ) and the clutch member ( 1 ) at the release point. In order to change the angle, a releasing member ( 3 ), developed for the method and mounted at the release point, is used, whereby the member has a vertical section (V) arranged intersectingly on the towing line at a height, which allows the towed device to pass below it. A safety system ( 9 ) can be connected to the releasing member, which system results in the stopping of the lift in the case that the load in the towing direction acting on the horizontal portion (V) exceeds the allowed value. By using this releasing method the dangers which are created if the release would occur too early or too late, are avoided.
