Conduit fitting with components adapted for facilitating assembly

A conduit fitting comprising:

• first and second fitting components that can be joined to define an internal cavity;
• a first ferrule and a second ferrule disposed in the internal cavity and aligned relative to an axis, the first ferrule comprising a camming surface at a back portion thereof, the second ferrule comprising a surface that contacts the camming surface when the first ferrule and the second ferrule are axially moved together along the axis;
• and
• a retaining structure that retains the first ferrule and the second ferrule together as a subassembly, the retaining structure comprising a flange extending radially outward and axially rearward from the back portion of the first ferrule to define an outer diameter recess;
• wherein the flange includes an end portion that extends radially inward to define an inner diameter recess retaining a forward portion of the second ferrule;
• and
• wherein the outer diameter recess and the inner diameter recess together define a hinge portion of the flange.
