Abstract
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.
