PURPOSE: A pipe connection device is provided to prevent deformation caused by an external impact by covering a connecting pipe with a protection member made of a strong material, and by fixing the connecting pipe with a joining member. CONSTITUTION: A pipe connection device(100) comprises a connecting pipe(110), a sealing member(120), a pressing member(130), a protection member(140), and a joining member(150). Expanded portions are formed in an end part of the connecting pipe, and pipes(10,10') are joined in the expanded portions. The sealing member is pressed to the connecting pipe and pipes by the pressure of the pressing member, thereby sealing the connecting pipe and the pipes. The pressing member presses the seal member with a pressing force. The protection member covers the connecting pipe and the joining member is joined to the protection member and presses the pressing member.
