PROBLEM TO BE SOLVED: To provide a steel pipe pile connection device capable of eliminating the welding work at site when piles are connected, facilitating positioning when piles are connected, and simplifying the connection work furthermore. SOLUTION: This pile connection device consists of a cylindrical hardware 3 whose one end is opened, in which an opening part 4 passing through in the axial direction is provided in a central part in the other end part, and which is formed into a thin-walled cylindrical wall 3c which can be fitted and inserted in an end part opening of a steel pipe pile main body by cutting over whole periphery of an outer peripheral face of a side peripheral wall on an opening end part side. It is provided with a plurality of substantially C-shaped engaging grooves 5 which pass through up to the opening part 4 in the radial direction toward the center of the opening part 4, in which a lower end face 3a of the cylindrical hardware 3 is opened along the radial direction, and which are formed at an interval in the circumferential direction in a lower end part of a side peripheral lower part 3b of the cylindrical hardware 3 and a substantially H-shaped connector 10 which is provided on the lower end face 3a of the cylindrical hardware 3 and connects steel pipe piles by fitting and inserting across a substantially H-shaped space part formed in a series by projecting and recessed parts 6, 7 which can be fitted in a projecting and recessed part of the mating and cylindrical hardware to be connected and the substantially C-shaped engaging grooves 5 of both cylindrical hardwares 3.
