One end of the tube facing the slit 4 provided in the longitudinal direction of the bellows tubes connected alternately by means has a first slope 5 inclined in a direction concave inward of the tube, and the other end of the tube facing the slit has a first slope 5 inclined in a direction concave inward. In a flexible bellows tube, the end has a second slope 6 inclined in a direction concave inward of the tube, and a V-shaped valley is formed by the first slope and the second slope. An extrusion-preventing bellows tube characterized in that a claw 7 facing toward the outside of the tube is provided at the tip of the second slope and faces the inner surface of the tip of the first slope.
