Abstract A passage (1) with monitored authorization of access is provided with a closure device using a barrier (2) hinged about a vertical axis γ. The passage includes at least one such barrier (2) with an end thereof situated adjacent to the vertical axis γ. Rectilinear guides (6 to 9) guide the axis γ along a line Δ parallel to the through direction of the passage. The barrier is further provided with a hinged link (4) which is hinged firstly about a vertical axis γ 1 situated along the barrier (2), and secondly about a vertical axis γ 2 situated in the vicinity of the line Δ. A drive system (10 to 13, 22 to 24) opens and closes the passage by causing the vertical axis γ to slide along the line Δ. The vertical axis γ is situated at a distance l from the line Δ. The length of the barrier (2) between the vertical axis γ and the vertical axis γ.sub. 1 is equal to L. The passage is characterized in that the length L 1 of the link (4) between the axes γ 1 and γ 2 is equal to L-∫, and in that the vertical axis γ 2 is tied to a carrier (15) supporting the hinge of the link (4). Further, the drive system (16 to 18) enables the carriage (15) to be displaced in a direction parallel to the line γ. Locks (19, 21) are provided for locking the carriage in two distinct positions along the stroke of the carriage (15).
