A device (100) for lifting and transport of a load hooked by a sling comprises a hook (10), a throat (11) of which is intended to receive a loop (90) or a ring of a sling, and comprises a ratchet (30) rotating between an open position in which an opening of the throat (11) is clear and a closed position in which the opening of the throat is blocked. The device further comprises: - a lock (40) having a locked position in which the lock prevents the rotation of the ratchet (30) in the closed position of the ratchet, and having an unlocked position in which rotation of the ratchet is possible; - a lever (50) having an armed position in which the lever holds the lock (40) in the unlocked position and a released position in which the lever does not hold the lock which is driven towards the locked position by a spring; and a rotation of the ratchet (30) from the closed position to the open position drives the lever (50) from the armed position to the released position. The device also allows the loop of the sling to engage on the hook without a particular action by pushing the ratchet which is automatically locked during the elastic return thereof.
