The invention concerns a device ( 16 ) for indicating incorrect closure of locking means consisting of a plurality of locking mechanisms ( 14 ) located between two fan cowlings ( 6 ) of an aircraft engine nacelle, the device including a body able to adopt, relative to the cowlings, a retracted position as well as a protruding position providing a warning of incorrect closure. According to the invention, the body of the device is able to cover at least partially at least two locking mechanisms ( 14 ) when it is in its retracted position, the retracted position being exclusively anthorised when each locking mechanism able to be at least partially covered by the body of the device is locked.

1. A locking assembly for securing two fan cowlings ( 6 , 8 ) of an aircraft engine nacelle, said locking assembly comprising:a locking means consisting of a plurality of locking mechanisms ( 14 , 14 a , 14 b ) located between said fan cowlings ( 6 , 8 ), each locking mechanism having a handle (
1. A locking assembly for securing two fan cowlings ( 6 , 8 ) of an aircraft engine nacelle, said locking assembly comprising:a locking means consisting of a plurality of locking mechanisms ( 14 , 14 a , 14 b ) located between said fan cowlings ( 6 , 8 ), each locking mechanism having a handle ( 15 a ); anda device ( 16 ) for indicating incorrect closure of said locking means, said device ( 16 ) including a body ( 18 , 118 , 218 ) able to adopt, relative to said cowling ( 6 , 8 ), a retracted position as well as a protruding position, the protruding position providing a warning of incorrect closure;wherein said body ( 18 , 118 , 128 ) in its retracted position is able to cover at least partially two of the locking mechanisms ( 14 , 14 a , 14 b ) spaced along a longitudinal axis of the engine, and wherein said retracted position is exclusively authorized when each of the locking mechanisms ( 14 , 14 a , 14 b ) that are able to be at least partially covered by the body ( 18 , 118 , 218 ) is locked. 2. A locking assembly according to claim 1, characterized in that each of the locking mechanisms ( 14 , 14 a , 14 b ) not locked and able to be at least partially covered by the body ( 18 , 118 , 218 ) of the device ( 16 ) constitutes a stop for the body ( 18 , 118 , 218 ), when moving the body from its protruding position to its retracted position. 3. A locking assembly according to claim 1, characterized in that with the body in its retracted position, the body ( 18 , 118 , 218 ) of the device ( 16 ) covers at least partially each one of the locking mechanisms ( 14 , 14 a , 14 b ) which constitute the locking means and is in contact with at least one of the said two cowlings ( 6 , 8 ). 4. A locking assembly according to claim 3, characterized in that said body ( 18 ) of the device ( 16 ) is mounted freely articulated from one end of one of said two cowlings ( 6 , 8 ). 5. A locking assembly according to claim 4, characterized in that the device ( 16 ) includes closing means ( 22 , 24 ) able to secure the said body ( 18 ) of the device ( 16 ) to the other of said two cowlings ( 6 , 8 ). 6. A locking assembly according to claim 1, characterized in that said body ( 18 ) of the device includes a first part ( 18 a ) intended to cover each of the locking mechanisms ( 14 ) constituting the locking means when said body ( 18 ) of the device ( 16 ) is in its retracted position, and a second part ( 18 b ) intended to warn of incorrect closure when said body ( 18 ) of the device ( 16 ) is in its protruding position. 7. A locking assembly according to claim 1, characterized in that said body ( 118 ) of the device ( 16 ) is mounted freely articulated from an external part ( 32 ) of said two cowlings ( 6 , 8 ). 8. A locking assembly according to claim 7, characterized in that the device ( 16 ) includes closing means ( 38 ) able to secure said body ( 118 ) of the device ( 16 ) to at least one of said two cowlings ( 6 , 8 ). 9. A locking assembly according to claim 8, characterized in that said body ( 118 ) of the device ( 16 ) is intended on the one hand to cover each one of the locking mechanisms ( 14 a , 14 b ) constituting the locking means when said body ( 118 ) of the device ( 16 ) is in its retracted position, and on the other hand to warn of incorrect closure when said body ( 118 ) of the device ( 16 ) is in its protruding position. 10. A locking assembly according to claim 1, characterized in that the body ( 18 , 118 , 218 ) of the device ( 16 ) includes means of enhancing its visibility. 11. A locking assembly according to claim 10, characterized in that each of the locking mechanisms ( 14 , 14 a , 14 b ) able to be at least partially covered by the body ( 18 , 118 , 218 ) of the device ( 16 ) includes a movable handle ( 15 a ) driving a hook ( 15 b ), said handle ( 15 a ) constituting, when the locking mechanism ( 14 , 14 a , 14 b ) is not locked, a stop for the body ( 18 , 118 , 218 ) of the de vice ( 16 ) when moving it from its protruding position to its retracted position. 12. A locking assembly according to claim 11, characterized in that the body ( 18 , 118 , 218 ) of the device ( 16 ) is able to cover a predetermined number greater than or equal to two locking mechanisms.
