ABSTRACT:
A conduit assembly has a visual inspection device. The visual inspection device is positioned within a connector housing. The device enables inspection of the connector to determine if proper connection between the housing and conduit has been achieved. The inspection device includes an annular member which, when in a vaulted position, exposes flags to indicate one position of the annular member to a substantially flat position concealing the flags to indicate a second position of the annular member.
