<p>PROBLEM TO BE SOLVED: To prevent rocking of a soft metal pipe caused by such as fluctuation of internal pressure of a soft metal pipe such as a copper pipe and an aluminum pipe, to increase durability by preventing breakage such as a crack of the soft metal pipe, and to increase productivity and connecting workability of a pipe connection tool by simplifying a structure thereof. SOLUTION: A pipe connecting structure for connecting ends of a soft metal pipe such as a copper pipe and an aluminum pipe. The pipe connecting structure comprises the soft metal pipe 10 and a pipe connecting tool 1. The pipe connecting tool 1 comprises: a short pipe portion 1a circumferentially fitted to the soft metal pipe 10 to be press-attached or press-contacted with a peripheral surface of the soft metal pipe 10; and a flange portion 1b extendedly disposed in an almost right angle direction of the short pipe 1a at a tip thereof. A base of the flange portion 1b of the pipe connecting tool 1 may have a U-shaped slot, which is formed along the peripheral surface of the soft metal pipe and is in a recessed shape.</p> |
