PROBLEM TO BE SOLVED: To provide a coupling releaser, capable of smoothly separating from each other, a pair of cylindrical pipes integrally coupled by easily releasing the engaged state of a member which is engaged with male and female engaging holes fitted to each other. SOLUTION: The coupling releaser 20 is used for releasing a coupling structure 10, in which a pair of cylindrical pipes 11 and 14 are coupled integrally in an axial direction by fitting a male engaging hole 12 to a female hole 15 and engaging a cylindrical sleeve 19, having an engaging pin 23 with an end 16 of the female-side hole from its outside; and the releaser has an inside guide face 26 which has a cross-sectional shape fitted to the outer peripheral face of the female hole end 16 and slidably guides the releaser 20 along the outer peripheral face, and also has a taped portion 28, which has a tip edge 27 having thickness which is insertable into the gap between the cylindrical sleeve 19 and the female-side hole end 16, and is made thick gradually rearward, while being slanted.
