In a joint mechanism as a pipe joint, an indicator ring is disposed between an end of a tightening cap and an outer wall portion of a body. The indicator ring is made up from a flat section that abuts against the body, an inclined section on an outer circumferential side of the flat section, and a protrusion formed on an outer edge portion of the inclined section. The protrusion is formed in parallel along an outer circumferential surface of the tightening cap. When the tube is connected, the inclined section is pressed by the end of the tightening cap, whereby the inclined section becomes substantially coplanar with the flat section. Concurrently, the protrusion projects toward an outer circumferential side of the inclined section. |

1. A pipe joint comprising a body including a flow path in the interior thereof through which a fluid flows, a tightening member that is screw-engaged and movable forward and backward on an end of the body and serves to connect a tube through which the fluid flows with respect to the end, and a confirmation ring, which is disposed between the body and an end of the tightening member, and is exposed to exterior with respect to the tightening member when the tube is tightened by the tightening member,
wherein at least one or more protrusions are included on an outer edge portion of the confirmation ring, and project diametrally outward with respect to the outer edge portion upon becoming deformed by being gripped between the tightening member and the body due to a tightening action of the tightening member. |
