PROBLEM TO BE SOLVED: To provide a connection tool which is used for a vertical plane such as an end panel of a vinyl house, and which is not torn even when a film material contacts thereto.SOLUTION: A connection tool comprises: a first semicylindrical part 11 extended in a first direction A1, and is along an upper half surface of a pipe material P1； a flat plate part 10 extended from a lower end part 11B of the first semicylindrical prat 11 to a lower direction, and has an almost square-shaped hole 14 formed on an almost center on a position below a center of the first semicylindrical part 11； a second semicylindrical part 12 extended from an end part 11C of the first semicylindrical part 11 to a second direction A2, and is along an upper half surface of a pipe material P2； a third semicylindrical part 13 extended from a lower end part 10B of the flat plate part 10 to a lower direction, and is along a lower half surface of the pipe material P2 by bending the flat plate part 10 along the lower half surface of the pipe material P1； and flange parts 15, 16 for tightening the second semicylindrical part 12 and the third semicylindrical part 13 each other at a position where the pipe material P2 is stridden over, when the flat plate part 10 is bent along the lower half surface of the pipe material P1 and the third semicylindrical part 13 is made to be along the lower half surface of the pipe material P2.SELECTED DRAWING: Figure 3【課題】ビニールハウスの妻面などの鉛直面に使用されてフィルム材が接触しても破れることがない連結具の提供。【解決手段】第１方向Ａ１に延び、パイプ材Ｐ１の上半面に沿わせる第１の半円筒部１１と、第１の半円筒部１１の下端部１１Ｂから下方向に延び、第１の半円筒部１１の中心よりも下の位置の略中央に形成された略方形の孔１４を有する平板部１０と、第１の半円筒部１１の端部１１Ｃから第２方向Ａ２に延び、パイプ材Ｐ２の上半面に沿わせる第２の半円筒部１２と、平板部１０の下端部１０Ｂから下方向に延び、平板部１０をパイプ材Ｐ１の下半面に沿って曲げてパイプ材Ｐ２の下半面に沿わせる第３の半円筒部１３と、平板部１０をパイプ材Ｐ１の下半面に沿って曲げて第３の半円筒部１３をパイプ材Ｐ２の下半面に沿わせた際に、パイプ材Ｐ２を跨ぐ位置で第２の半円筒部１２と第３の半円筒部１３とを互いに締め付けるためのフランジ部１５，１６とを含む。【選択図】図３
