摘要

The device (10) has a retaining body formed of an electric vent (44) and electrically connected to a detection unit formed of an electronic board (32) and a coil (30). The retaining body takes a locking state in case of absence of a default signal, and takes an unlocking state in case of presence of the default signal. The retaining body retains a retaining element i.e. ejection flap, in the nominal position when the retaining body is in the locking state. The retaining body liberates the retaining element when the retaining body is in the unlocking state.
