Abstract: The guiding device (2) according to the invention comprises an essentially U-shaped guiding groove for guiding a first rope (6), two guiding lumens (7) for guiding a closed loop of a second rope (8) for securing the guiding device on a fixed attachment point (9) or on a mobile part to be handled, the two guiding lumens (7) extending on both sides of the plane defined by the guiding groove (5), and a fixation tab (11) of the closed loop of the second rope (8) on the guiding device. The guiding device (2) also comprises first and second passage openings (15) each respectively emerging in one of the guiding lumens (7), each of the first and second passage openings (15) being arranged to allow the insertion of the second rope (8) into the corresponding guiding lumen.
