Abstract: The present invention relates to a pipe connection apparatus. In accordance with an embodiment of the present invention, the pipe connection apparatus comprises: a tube-shaped inner supporter inserted into pipes to be connected; a connection joint fastened to the outer circumference of the pipes; and a ring-shaped tightening member fastened on the outer circumference of the connection joint, being engaged with the pipes. The tube-shaped inner supporter includes a ring-shaped first outer bump protruding from the outer circumference to match the inner diameter of the pipes, and has a lower ductility than that of the pipes. The connection joint accommodates and is engaged with the pipes, and has an engagement unit which has a lower ductility than that of the pipes. In the connection joint, there are ring-shaped protruding first inner bumps formed along the inner circumferential surface of the engagement unit to match an outer diameter of the pipes, and an outer diameter of the engagement unit is smaller than the inner diameter on a front side and greater than the inner diameter on the rear side based on the fastening direction of the tightening member. The tightening member is fastened by compressing the outer circumference of the engagement unit, and has a smaller inner diameter on a rear side than that of a front side, and a lower ductility than that of the engagement unit. There are first outer bumps of the tube-shaped inner supporter placed in a section corresponding to the parts between the first inner bumps of the connection joint, and a base width of each of the first inner bumps is smaller than that of the first outer bumps. As the tightening member compressing the outer circumference of the engagement unit is fastened, the engagement unit and the pipes are plastically deformed, and the pipes are bent to be engaged with the first outer bumps in the sections between the first inner bumps, so the pipe connection apparatus comes to be engaged with the pipes. The present invention aims to provide a pipe connection apparatus which is able to improve airtightness and be easily fastened.
