Abstract
An insertion indication device for use with a quick connect fitting includes a generally annular base member which is adapted for positioning about a male conduit inside of a connector housing. One or more leg members extend axially from the base member and terminate near an axial opening formed in the housing for receiving the conduit. A generally annular indicator member positioned adjacent to the opening releassably engages the end members. Upon couplings of the male and female elements of the quick connector, the indicator member is separated from the leg members to provide visual conformation that coupling has taken place.
