The metal plate as a whole is bent into a U-shape, and the tip of the biped plate has a wedge structure with a slope (for example, Japanese Utility Model Application Publication No. 59-75905, Japanese Utility Model Application No. 59-75

作用を第２の結合金具が行う。 In the prior art, when the second fitting is fitted into a required part of the first fitting and pushed between the first pipe and the second pipe which intersect with a space in between, the second fitting fits into the required part of the first fitting. Under the condition that the outer surface of the groove-shaped base of the U-shaped bend of the coupling fitting is in contact with the peripheral surface of the pipe on the side facing this, the slope-shaped tip end surface of the bipod plate can bend the pipe on the side facing this as required. The second coupling fitting performs a wedging action of pushing it to the side.

に対し逃げることを意味し、パイプの強固な締付
けが行われない。 That is, in the second coupling fitting, the distal end surface of the bipedal plate, which is bent in a U-shape as a whole, contributes to wedge tightening of the intersecting pipes. For this wedge tightening to be successful, the slopes of each tip of the bipod must be parallel. However, even if the biped plates are parallel when the metal fittings are first manufactured, due to repeated use of the metal fittings (this kind of metal fittings are used in this way), etc., the biped plates are deformed and become parallel. There is a high possibility that this will not occur, and there is no guarantee that good wedge tightening will always be obtained. In addition, since the second coupling fitting is bent in a U-shape as a whole, when the second coupling fitting is pushed between the intersecting pipes, the push-in resistance causes the biped plate of the fitting to expand or expand. On the contrary, there is a strong tendency to deform. When such deformation occurs, it means that the biped plate pipe escapes, and the pipe cannot be firmly tightened.
