PROBLEM TO BE SOLVED: To provide pipe-like joint hardware for a framework material of a wooden building, which can be manufactured at a low cost and which is provided with the same joint function as the conventional example. SOLUTION: The upper end of the pipe-like joint hardware is inserted into one framework material 50 and the lower end of the pipe-like joint hardware is inserted into the other framework material 60. Then fixing levers 70, 80 such as a drift pin are engaged with and inserted into insertion holes 10, 12 through through-holes 50b, 60b provided to the framework materials 50, 60, and the pair of framework materials 50, 60 are joined together. Through-holes 10', 12' are provided in the center of a longitudinally rectangular metal sheet Aa in the breadth direction which undergoes a bending deformation in a pipe shape. Through-holes are formed by bringing half-round notches 4B, 4'B and 7B, 7'B into agreement with each other respectively, and the half-round notches 4B, 4'B and 7B, 7'B are each provided on both ends along the longitudinal direction of the metal sheet. The insertion holes 10, 12 are formed by bringing the through-holes 10', 12' and the through-holes into agreement with each other in the longitudinal direction. Then the contact sections of both ends of the metal sheet Aa which are formed by engaging square projection pieces 5A, 8A, 3A, 6A and square notches 5B, 8B, 3B, 6B provided on the other end with each other are provided on both the upper and lower sides of the insertion holes 10, 12.
