A device for lifting and transporting a load attached by a sling includes a hook comprising a throat opening intended to receive a loop on a sling. The device includes a latch that can pivot between an open position and a closed position in which said throat opening is obstructed. The device includes a locking device including a locked position in which said locking device prevents the latch from turning in the closed position, and an unlocked position in which the latch can rotate; a lever including a loaded position in which said lever holds the locking device in the locked position and a released position in which said lever does not hold said locking device. A rotation of the latch from the closed position to the open position triggers the lever from the loaded position to the released position.
