PROBLEM TO BE SOLVED: To provide a low-cost and simple structured tube connecting structural body which can directly connect a resin tube and a pipe-shaped mate member holding ring-shaped elastic sealing members between them and is excellent in sealing ability. SOLUTION: A cylindrical base section 21 of an engaging member 2 is secured to the external peripheral surface of an end of a resin tube 1 and is fixed to the resin tube 1 whose diameter is broadened by the cylindrical press fitting member 3 pressedly fitted in the internal surface of the end section. This engaging member 2 has a plurality of arm sections 23 axially extending from the cylindrical, and the first claw-shaped engaging section 24 protrudedly provided at its tip and the second engaging section 512 of a pipe-shaped mate member 51 are engaged with each other in snap relation, and the pipe-shaped mate member 51 and the resin tube 1 directly connected to each other holding a ring-shaped elastic sealing member 4 between them. |
