A locking device includes a locking pair having a bolt to engage with a retainer and a detection linkage. The bolt is movably mounted against a spring which tends to return the bolt to a position spaced apart from the retainer. The detection linkage is also movably mounted between an unlocked position where the detection linkage allows unlocking of the bolt and the retainer. In particular, a portion of the bolt then engages with the detection linkage by means of a detecting part of the detection linkage to block a possible return of the detection linkage towards a locked position where the detection linkage engages with the portion of the bolt so as to oppose to unlocking of the bolt. The detecting part irreversibly drives the detection linkage to its unlocked position even when one locking pair is unlocked.

1. A locking device for locking between a first structure and a second structure, said locking device comprising several locking pairs arranged along a locking line and connected by a linkage structure, each locking pair comprising at least one bolt connected to the first structure and adapted to engage with at least one corresponding retaining means which is connected to the second structure, the at least one bolt being further movably mounted against at least one elastic return means which tends to return the at least one bolt to a position spaced apart from the retaining means, said locking device further comprising an indicator connected to the linkage structure, the indicator providing an indication of a locked position and an unlocked position of all the locking pairs,the linkage structure including at least one detection linkage, the at least one detection linkage extending through the locking pairs to always connect the locking pairs together and to connect the locking pairs to the indicator, the linkage structure movably mounted between a unlocked position where the at least one detection linkage allows unlocking of the at least one bolt and the at least one corresponding retaining means, at least a portion of the at least one bolt then engaging with the detection linkage so as to block a possible return of said detection linkage towards a locked position where the detection linkage engages with said at least the portion of the at least one bolt so as to oppose unlocking of the at least one bolt,wherein said at least the portion of the at least one bolt engages with the detection linkage by means of at least one detecting part of said detection linkage, said at least one detecting part being movably mounted between a locked position, corresponding to the locking of the locking pair, where the at least one detecting part allows the locked position of the detection linkage and is adapted to be driven by the at least one bolt towards an unlocked position where the at least one detecting part drives the detection linkage to the unlocked position of the detection linkage, a shifting of the detection linkage to the unlocked position being thus provided when one locking pair is unlocked,wherein the indicator provides an indication if not all locking pairs are locked. 2. The locking device according to claim 1, wherein the at least one detecting part engages with the detection linkage through a fork adapted to cooperate with a corresponding shoulder of the detection linkage. 3. The locking device according to claim 1, wherein the at least one detecting part is pivotally mounted to tilt between a first and second positions. 4. The locking device according to claim 1, wherein the detection linkage is mounted against an elastic member which tends to bring the detection linkage back to the locked position. 5. The locking device according to claim 1, wherein in the locked position of the detection linkage, the at least one detecting part abuts against a portion of the at least one bolt. 6. The locking device according to claim 1, wherein the at least one bolt is in the form of a bracket for removably engaging a hook of the at least one corresponding retaining means. 7. The locking device according to claim 1, wherein the at least one corresponding retaining means has a shape of a hook. 8. The locking device according to claim 1, wherein the at least one bolt is adapted to drive the at least one detecting part by means of a translatably movable shaft. 9. The locking device according to claim 8, wherein the translatably movable shaft is movably mounted with the at least one bolt. 10. The locking device according to claim 1, wherein the indicator is a mechanical panel having a hidden position and a protruded position, wherein the panel cannot return to its hidden position if all locking pairs are not locked. 11. The locking device according to claim 1, wherein the indicator is electrical and uses linkage proximity sensors to send corresponding electrical signal to LEDs. 12. The locking device according to claim 1, wherein the at least one detection linkage has opposing ends, one of the opposing ends of the at least one detection linkage being removably connected to the indicator and the other of the opposing ends of the at least one detection linkage being connected to the locking pairs. 13. The locking device according to claim 1, wherein the one of the opposing ends of the at least one detection linkage is movable toward or away from the indicator. 14. The locking device according to claim 1, further comprising a latch connected to the one of the opposing ends of the at least one detection linkage. 15. The locking device according to claim 1, wherein the at least one detection linkage includes a cable extending through the locking pairs.
