Abstract
An insertion indication device for use with a quick connect fitting includes a generally annular base member which is adapted for positioning about the male portion of the fitting within the female portion such that in a first position the annular member is disposed between a step formed in the axial female portion opening and a tapered male portion retaining element, and in a second position the annular member is disposed between an abutment surface formed by the retaining element and a housing seat formed within female portion. A number of circumferentially spaced, axially extending legs are visible prior to engagement of the fitting and are hidden from view upon full engagement thereof.
