Patent attributes
An easily usable quick connector includes a connector body 12, a retainer 16, and a complete connection indicating member 28 capable of being repeatedly used for indicating if a tube 14 has been inserted in the connector body 12 with an end part thereof provided with an annular ridge 15 locked in place by the retainer 16 at a position for complete connection. The complete connection indicating member 28 is combined with the connector body 12 so as to be movable into the connector body 12. The complete connection indicating member 28 can be completely pressed into the connector body 12 only when the end part of the tube 14 is inserted in the connector body 12 so that the locking tongues 24a and 24b of the retainer 16 are engaged completely with the annular ridge 15 of the tube 14.
