This pipe fitting (10) has a housing (20), a first retainer (30), and a second retainer (40). The first retainer (30) has first elastic pieces (33) as well as being slidably disposed inside the housing (20) and being configured so that when the first retainer (30) is located on the connecting section (21)-side of the housing (20), the first elastic pieces (33) are expandable and when the first retainer (30) is located on the inserting section (23)-side of the housing (20), expansion of the first elastic pieces is restricted. An operating pipe section (43), which can be held at the connecting section (21)-end only through an opening (22) in the connecting section (21) of the housing (20) is provided on the second retainer (40). |
