PROBLEM TO BE SOLVED: To provide a connecting structure of a pipe, capable of smoothly disassembling a pair of connected cylindrical pipes by easily releasing a locking state of an engagement projection locked in aligned engagement holes. SOLUTION: In this connecting structure 10 of the pipe where a sleeve member 19 having the engagement projection 17 projecting from its inner peripheral surface is attached from an outer side, and the engagement projection 17 are locked in the aligned engagement holes 15, 16 to axially connect and integrate the pair of cylindrical pipes 11, 12, the sleeve member 19 is composed of a sleeve body 21 extending at both sides of the engagement projection 17 along an outer peripheral face of a female-side end 14, and closely kept into contact with an outer peripheral face while remaining a clearance 18 between both circumferential ends 20, and a pressing body 26 composed of a pair of supporting leg portions 22 and a pressing portion 23, and disposed in a state of keeping a space 25 between the pressing portion 23 and an outer peripheral face of the female-side end 14 by joining tip portions of the pair of supporting leg portions 23 to both end portions 24 of the sleeve main body at a position opposed to the engagement projection 17.
