Passage corridor 1 comprising a blocking device 4 comprising a turnstile 9 linked to a lateral post 2 delimiting the said corridor on one side, the turnstile edges formed by three arms 10, 11, 12 assembled into the three legs of a regular trihedron and comprising a rotation axis DELTA which is coincident with the ternary symmetry axis of the turnstile, rotation of the turnstile being normally blocked and its rotation by 2 pi /3 being made possible by validation by an access authorisation system, characterised in that the blocking device further comprises a gate 14 which is articulated to the said post around an axis DELTA 1 contained in the vertical plane containing the rotation axis of the turnstile, the gate having space cut out so as to allow the arms of the turnstile to pass, and having sufficient height to prevent an individual from easily stepping over it, the said gate being equipped with a device 19 for return into position barring the corridor and comprising an automatic locking mechanical device 16 linking the gate, when it is in position barring the corridor, to that of the three arms of the turnstile which is also in position barring the corridor, the device automatically unblocking during rotation of the turnstile and the simultaneous opening of the gate when simply pushed by a user. <IMAGE>
