PROBLEM TO BE SOLVED: To provide a pipe material connecting structure, attached in an optional position of at least one of pipe materials and firmly fixes the pipe materials when the pipe materials are connected to each other via a joint. SOLUTION: In this pipe connecting structure, mutually perpendicular coated resin pipe materials are connected via the joint. The joint includes a core cylinder part for inserting one of the pipe materials, and a projecting cylinder part for supporting one end of the mutually perpendicular other pipe material. The core cylinder part is formed by combining divided joints divided into a plurality of pieces so that the core cylinder part interposes the pipe material. A projected line is projected on an inner circumferential surface of the core cylinder part, wherein the projected line has a chevron shape, a truncated chevron shape in which a bent part of the chevron shape is separated, a triangle shape or a diamond shape in which both ends of the chevron shape are connected, or a shape in which these shapes are appropriately combined.
