The invention relates to a locking device (9) designed to be arranged in a junction region of a nacelle, comprising a locking system (10), intended to be mounted on a first half-shell of the nacelle, engaging with a retention member (11) intended to be mounted on a second half-shell, the locking sys
The invention relates to a locking device (9) designed to be arranged in a junction region of a nacelle, comprising a locking system (10), intended to be mounted on a first half-shell of the nacelle, engaging with a retention member (11) intended to be mounted on a second half-shell, the locking system (10) being actuable between a locked state and an unlocked state with respect to the retention number (11), the locking system (10) and the retention member (11) being movable with respect to one another between a drawn-together position in which they can be locked with respect to one another and a spaced-apart position. The locking system (10) and/or the retention member (11) comprise locking means (25) designed to allow the locking system (10) to be locked with respect to the retention member (11) when they are in the drawn-together position and to prevent them from being locked when they are in the spaced-apart position.

1. A locking device designed to be placed in a junction zone of a nacelle, the locking device comprising: a locking system, designed to be mounted on a first half-shell of the nacelle, interacting with a retention member designed to be mounted on a second half-shell, the locking system being able to be actuated between a locked state and an unlocked state relative to the retention member, the locking system and the retention member being able to be moved relative to one another between a drawn-together position of the latter in which they can be locked relative to one another and a separated position of the latter, the locking system and/or the retention member comprising immobilization means, designed to allow the locking of the locking system relative to the retention member when the latter are in the drawn-together position, and to prevent their locking when the latter are in the separated position, the locking system comprising a hook capable of engaging with the retention member, and an operating member interacting with the hook so as to achieve the engagement or the disengagement of the latter relative to the retention member when the operating member is actuated,wherein the immobilization means comprise linking means connected to the operating member and moved when the latter is actuated, and a member forming a movable stop that can be moved between an immobilization position in which the linking means rest against the member forming the movable stop when the operating member is actuated, and a release position in which the member forming the movable stop is separated from the trajectory of the linking means when the operating member is actuated, the member forming a movable stop being fitted with at least one actuation lug having an actuation end, the retention member comprising at least one pin the free end of which rests against the actuation end of the lug, in the drawn-together position of the locking system and of the retention member, in order to move the member forming a movable stop to the release position. 2. The device as claimed in claim 1, wherein the linking means comprise an arm protruding outward, the member forming a movable stop taking the shape of a movable clapper fitted with a hook forming a stop. 3. The device as claimed in claim 1, wherein the member forming a movable stop is subjected to elastic return means suitable for moving it to the immobilized position. 4. The device as claimed in claim 1, wherein the hook comprises a curved end capable of engaging with the retention element, the hook being mounted so as to pivot about an end spindle situated opposite the curved end, the locking system comprising a main spindle, designed to be fixedly attached to the first half-shell, an articulation comprising at least one compression link rod mounted so as to pivot about the main spindle and an intermediate spindle positioned between the main spindle and the end spindle, the linking means having a first branch designed to interact with the member forming a movable stop and a second branch connected to the first via a middle zone, the middle zone of the arm being mounted so as to pivot about the end spindle, the second branch being mounted so as to pivot about the intermediate spindle. 5. The device as claimed in claim 1, wherein the member forming a movable stop is mounted so as to pivot about an articulation spindle designed to be fixed relative to the first half-shell. 6. A turbojet nacelle comprising a forward air-intake section, a middle section designed to surround a fan of the turbojet, and an aft section formed from at least one first and one second half-shells mounted rotatably on a pylon so as to be able to be deployed each between a working position in which the half-shells are drawn together and a maintenance position in which the half-shells are separated from one another, characterized in that the nacelle is fitted, in a junction zone of the two half-shells, with at least one locking device as claimed in claim 1, the locking system being mounted on the first half-shell, the retention member being mounted on the second half-shell. 7. An aircraft employing at least one nacelle with the locking device as claimed in claim 1.
