The device has a sliding door (11) parallelly displaced along a longitudinal axis of a sliding beam (2). A releasable unit (12) is adapted to grip the beam with the door to displace the door with the beam or to displace the beam without driving the door. A door maintenance unit maintains the door in a vertical plane parallel to a displacement plane of the beam and a bolt. The beam has a tubular groove indirectly and locally extending according to a displacement axis of the beam. |
