<p>PROBLEM TO BE SOLVED: To fix a saddle coupling, having a branch pipe connection part, at a part, where the branch pipe of the piping is arranged, without using a jig for an exclusive use and in a state that the inner surface of the saddle coupling is relatively adhered. SOLUTION: A saddle coupling body 11 is formed in the shape of a cradle having two side plates positioned astride a part where the branch pipe of a piping 4 is arranged. A through-hole 111a is formed in one side plate 111 of two side plates and a male screw 112a is formed in the other side plate 112. A pin 12 at the tip part of which a male screw 121 is formed and having a taper surface 123 the size of which is gradually increased from the tip part toward the pin head part of a base end part is joined in a screwed-in state with a female screw 112a formed in the other side plate 112 in a state to be inserted through the through-hole 111a of one side plate 111.</p> |
