Abstract
A quick-connect coupling has a retainer for retaining a tube in a coupling body. The retainer is pressed in the coupling body so as to lock the tube in place in the coupling body. The retainer cannot be fully pressed in the coupling body and projects from the coupling body to indicate that the tube is not properly connected to the coupling body unless the tube is inserted completely in the coupling body. The retainer is combined with complete connection verifying legs that enables the retainer to be able to be pressed in the coupling body when an annular ridge formed in an end part of a tube inserted in the coupling body is advanced beyond a position where the retainer is able to engage with the annular ridge.
