To reduce a burden of a worker relating to connecting work of duct such as air-conditioning/ventilation ducts disposed above a head such as a ceiling.SOLUTION: A duct device 1 is equipped with a first duct 10 formed in a cylindrical shape, and a connector 30 that is attached to a tip end portion of the first duct 10, and is compressed between an inner surface of the first duct 10 and an outer surface of a second duct when the second duct formed in a cylindrical shape is inserted in the first duct 10. The connector 30 includes a rod-shaped body part 31, and a groove part 33 that is formed on the body portion 31, extends in a longitudinal direction, and is fitted with a tip end portion of the first duct 10. The groove part 33 is fitted with the tip end portion of the first duct 10 while bending the body part 31.SELECTED DRAWING: Figure 4 【課題】空調・換気用のダクト等、天井のような頭上に配置されるダクトの接続作業に係る作業者の負担を軽減可能にする。【解決手段】ダクト装置１は、筒状に形成された第１ダクト１０と、第１ダクト１０の先端部に取り付けられ、第１ダクト１０の内部に、筒状に形成された第２ダクトを挿入したときに第１ダクト１０の内面と第２ダクトの外面との間で圧縮される接続具３０と、を備える。接続具３０は、棒状の本体部３１と、本体部３１に形成され、長手方向に沿って延びかつ第１ダクト１０の先端部に嵌合する溝部３３と、を含んで構成され、本体部３１を湾曲させながら溝部３３が第１ダクト１０の先端部に嵌合されている。【選択図】図４
