The door threshold for a railway vehicle is intended to partially fill the gap between the vehicle and a platform. It comprises a support ( 22 ) which can be connected to the structure ( 16 ) of the railway vehicle and a strip ( 24 ) which is retained by the support ( 22 ). The strip ( 24 ) can be displaced between a normal position, in which it projects relative to the support ( 22 ), and a position retracted in the support ( 22 ). It comprises means ( 30 A, 30 B) for clamping the strip against at least a clamping surface ( 30 A, 30 B) of the support in order to produce friction of a specific value between the strip ( 24 ) and the support ( 22 ) counter to the displacement of the strip ( 24 ) relative to the support ( 22 ) in the plane of the or each clamping surface ( 30 A, 30 B).
