A tandem pulley includes a support bracket having the shape of an inverted U. The support bracket defines a through hole. A pair of sheaves is arranged in line inside the support bracket. Each sheave is mounted rotating freely around a spindle fixed to the support bracket. A carabiner is fitted in the through hole. A connector is configured to connect the support bracket with the carabiner. The connector is configured in such a way as to allow rotation of the carabiner around an axis parallel to the spindles of the pair of sheaves. A spring is connected to the support bracket, the spring being arranged to exert a force on the carabiner biasing the latter to a rest position by rotation of the carabiner.
