Abstract

A quick connector has a housing, a retainer for locking a tube at a correct position for complete connection in the housing and a restraining ring for restraining the retainer from being pressed into the housing to its locking position unless the tube is inserted in the housing and placed at the correct position for complete connection to avoid connecting the tube to the quick connector in a falsely locked state. The restraining ring is provided with locking bars that engage with the legs of the retainer to restrain the retainer from being pressed into the housing. The locking bars permit releasing the restraining ring to its releasing position to enable the retainer to be pressed into the housing to the locking position.
