LOCKING DEVICE WITH MECHANICAL DETECTION OF CLOSING AND OPENING
The present invention relates to a locking device (10) comprising a locking pair (11) comprising a bolt (112) capable of engaging with a retaining means (111), the bolt being movably mounted against an elastic return means (113) that tends to return it to a position spaced apart from the retaining means, said device comprising a detection linkage (15), which is moveable between an unlocked position and a locked position, characterised in that the part of the bolt engages with the linkage via at least a detection part (200) movably mounted between a locked position, corresponding to a locking of the locking pair in which it allows the locked position of the linkage and is capable of being driven by the bolt to an unlocked position in which it drives the linkage non-reversibly to its own unlocked position.
