1. A device for detecting an absence of a mechanical barrier for a missile, the device comprising:
at least one rod constrained by a first elastic element and provided with an end referred to as free capable of coming into contact with the mechanical barrier, and
at least one cam constrained by a second elastic element, the rod and the cam being configured so that the rod can assume one of the following positions:
a position referred to as an initial entry position (P1), wherein the rod is held in a stable position between the cam and the mechanical barrier;
a position referred to as an extended position (P2), into which the rod is brought under an action of the cam by a displacement in a direction (E) of a free end, in the absence of the mechanical barrier; and
a position referred to as a final entry position (P3), into which the rod is brought under an action of the first elastic element, after release of the displacement of the rod by the cam.
