PIPE ARRANGEMENT CONNECTION CONSTRUCTION

PROBLEM TO BE SOLVED: To provide a pipe arrangement connection construction which prevents an O ring for a seal from being protruded from a retention groove on the occasion of connecting pipe arrangement even though a resin piping is obliquely cut when performing connection by cutting the resin piping at installation field etc. SOLUTION: In the pipe arrangement connection construction which seals on a tubular body 18 providing on a piping joint 10 by O rings 24-1, 24-2 attaching on outer peripheral face of the tubular body 18 between the resin piping 20 inserted over from axial direction in outer fitted condition and the tubular body 18, the construction is configured to fit a coiled spring 54 on outer peripheral side of the O rings 24-1, 24-2, to bring end face 54A into contact with tip surface 20A over entire periphery by deforming to follow the coiled spring 54 in the shape of the tip surface 20A of the resin piping 20 when inserting over the tubular body 18 of the resin piping 20 and thus to prevent the O rings 24-1, 24-2 from overhanging.
