摘要

The lock has a housing, a locking bar, a holder for locking the bar in its closed position, a sensor for monitoring the bar locking position with first and second transponders attached to the bar and holder that emit first and second identification signals and an interrogation head fixed to the housing so as to only receive the identification signal from a transponder if the bar is in its closed position and locked by the holder. The lock has a housing (26), a locking bar (22), a holder (34) for locking the bar in its closed position and a sensor (44) for monitoring the bar locking position. The sensor has a first transponder (46) attached to the bar that emits a first identification signal, a second transponder (48) attached to the holder that emits a second identification signal and an interrogation head (50) fixed to the housing so as to only receive the identification signal from a transponder if the bar is in its closed position and locked by the holder.
