A flareless pipe coupling structure according to one embodiment of the present invention includes a fitting main body 1, a coupling member 2 threaded to the fitting main body 1, and a ferrule 3. The ferrule 3 is located forward of a pipe coupling portion 23 of the coupling member 2. A partition lid 4 serving as a protective member is detachably mounted to the pipe coupling portion 23 to cover the ferrule 3. The partition lid 4, which closes a pipe insertion port 16 when no pipe is connected, can function as a protective member. The partition lid 4 includes, for example, a cylindrical wall 42 having an internal space for accommodating the ferrule 3, and a closing wall 41 that closes one end of the cylindrical wall 42 and closes the pipe insertion port 16 of the fitting main body 1. |
