1. An uplock for the selective retention of a capture pin of a movable element, the uplock comprising:
a hook which is movable between a release position and a position for retaining a capture pin of the movable element;
a locking member interacting with the hook and movable between a locked position in which it immobilizes the hook in the retaining position, and an unlocked position in which the hook is free to be displaced under the force of the capture pin of the movable element;
detection means adapted to detect a situation in which the hook is in the retaining position and if the capture pin is present in the hook;
characterized in that the detection means comprise a sensor and a target which are movable relative to each other between a proximate position and one or more positions which are remote from each other, one of the target or the sensor being carried by the locking member and the other of the target or the sensor being carried by an indicator lever which interacts with the capture pin and which is movable between a first position which is indicative of the absence of the capture pin in the hook and a second position which is indicative of the presence of the capture pin in the hook, so that the target and the sensor are only in the proximate position if the locking member is in the locked position and if the indicator lever is in the second position which is indicative of the presence of the capture pin in the hook.
