A double-reeved lifting device includes a lower reeve block secured to a lifting hook and an upper reeve block, wherein the two reeve blocks include reversible connection means adapted to be reversibly configured between a connected configuration and a disconnected configuration. The reversible connection means include a locking mechanism and a complementary locking structure respectively having at least one striker orifice and a bolt slidably movable and supporting a locking finger adapted to rotatably cooperate with the striker orifice, and respective guide elements cooperating together so as to convert a relative approach and a relative distancing between the two reeve blocks into concomitants slidings and rotations of the bolt.
