The plug has a body portion received in the accommodation recess, and an anchor portion extending axially from the body portion. The body portion of the plug has an outer diameter larger than a distance between the restricting sections of the flange, and the anchor portion of the plug has a radius larger than a radius of curvature of the arc section of the flange such that the plug can be firmly retained in the accommodation recess of the housing when the plug is not in use.
