AIR CONDITIONING FLEXIBLE DUCT

摘要

PROBLEM TO BE SOLVED: To provide an air conditioning flexible duct capable of conducting a connecting work of a high strength by a one-touch operation type by providing a clamping band in a non-bulky state around the duct. SOLUTION: A shape retaining wire 1d is integrally sealed except a part of a connecting cylinder 1e to be externally inserted to a connecting ring 51 of a chamber box 50, and a clamping band 3 as a ring-like material with a fastener 4 of the shape substantially fitted in a wire material 3a such as a wire or the like and an outer periphery of the cylinder 1e is provided around the cylinder 1e. The fastener 4 is a plate-like material plastically deformable along the outer periphery of the cylinder 1e and foldable at a mid way of a circumferential direction as a bending point. When one side partitioned at the bending point of the fastener 4 is bent in a direction separating from the outer periphery of the cylinder 1e and superposed, a clamping force of the band 3 is held by a tension of the material 3a.
