Abstract: The movable class-partitioning divider for an illustrative airliner passenger cabin comprises in particular: a device to lock said divider into a mooring adapter selected during the translation of the divider along a guide rail configured longitudinally in said cabin and unlocking it before such translation takes place; a device connecting at least one first connector, which is firmly affixed to a movable support mounted on a longitudinal rail solidly joined to the cabin, to a second connector solidly which is firmly affixed to said mooring adapter; a device operating said locking and connecting devices during translational operation; a device to preclude actuating said operating devices as long as at least the first connector is outside a given connection zone to said second connector firmly affixed to said mooring adapter. Application: passenger transportation.
