A joint which is a cylindrical body having an inner circumferential surface, a diameter of which is larger than any of outer diameters of two pipes to be connected, the cylindrical body being provided with an annular projecting strip portion formed in an approximately axially intermediate portion so as to project radially inward, first and second cylindrical portions respectively disposed on opposite sides of the annular projecting strip, annular projecting portions projecting radially outward so as to form annular space portions in approximately intermediate portions of the first and second cylindrical portions respectively, and through holes formed respectively in the annular projecting portions for injecting a foamable and curable liquid agent. A method of connecting pipes by use of the above pipe joint, includes the steps of bonding sealing bodies of a compressible and deformable material onto the outer circumferential surfaces of the two pipes to be connected or the inner circumferential surfaces of the joint; pressing the pipes into the joint; injecting a foamable and curable liquid agent into inside space portions through corresponding through holes so as to fill the internal space portions with a foamed and expanded hardened substance of the liquid agent injected therein to thereby connect the pipes to the joint water-tightly.
