Abstract: Device (1) for attaching a load to a cable (22) or any other elongate element, comprising a first and a second coaxial wheel having star-shaped branches (5, 6) and a shoe (9) which is mounted on the branches of the wheels, in such a way that these can rotate relative to the shoe, the cable (22) being intended to pass between the wheels (2, 3) and under the shoe (9). The space (28) between two of the branches of the first wheel (2) is shaped in such a way that, when the cable (22) arranged between the wheels is engaged laterally into this shaped space (28), the shoe (9) can pass over the cable (22), at the same time crossing the shaped space (28), so that the cable (22) and the device (1) can be coupled or uncoupled.
