Retainer and pipe joint using retainer

A pipe joint comprising a pipe joint body housing a retainer having a shape of a ring adapted for insertion of a flexible pipe with a corrugated pipe formed into a corrugated pattern in an axis direction that makes the retainer available in a pipe joint connected to the flexible pipe, the retainer comprising:

• a plurality of pawls adapted to engage a valley of the corrugated pattern of the corrugated pipe;
• a plurality of supports that contact an inner surface of a pipe joint body housing the retainer in the pipe joint, the supports being continuous with corresponding ones of the pawls as viewed in a direction of a center axis of the ring of the retainer;
• and
• a connector connecting the pawls and the supports in a plurality of combinations continuous with each other, wherein
• the connector is more deformable than the pawls and the supports, and
• when the retainer is not subjected to external force, a distance between the center axis of the ring of the retainer and each of the plurality of the pawls is less than a distance between a center axis of the corrugated pipe and a corrugated peak of the corrugated pipe,
• wherein the connector includes:
• a first section extending toward a first combination that is one of two combinations each including a pawl of the plurality of pawls and a support of the plurality of supports and arranged across the connector, the first section being connected to the first combination;
• and
• a second section extending toward a second combination that is another of the two combinations, the second section being connected to the second combination,
• wherein the first section and the second section extend in differing directions.
