PROBLEM TO BE SOLVED: To provide a connecting structure of a pipe capable of effectively preventing generation of looseness and damage in a connected part even by applying bending stress to the connected part also capable of easily connecting a pair of the cylindrical pipes integrally formed in an axial direction by a simple structure. SOLUTION: In this connecting structure 10, inserting a diametrically contracted end part 13 of one cylindrical pipe 11 into an opening 15 in an end part 14 of the other cylindrical pipe 12 to obtain a connection part 16 to cover it to arrange a sleeve member 17 to use it to connect a pair of the cylindrical pipes 11, 12 integrally formed in an axial direction, protrusion insertion holes 18, 19 are respectively formed in each end part 13, 14 of a pair of the cylindrical pipes 11, 12 constituting the connection part 16, the sleeve member 17 is provided with an elastic part 20 deformed in the diametric direction outward to generate energizing force in the diametric direction inward, the protrusion insertion holes 18, 19 are conformed to insert an engaging protrusion 21 locked to the protrusion insertion holes 18, 19.
