The elastic annular band designed to bind the flat spring sections together while surrounding the outer surfaces thereof over a given range in order to bring the contact sections into contact with the outer surfaces of the test tubes. The projections projected from the outer surfaces of the flat spring sections to hold the elastic annular band in a given position.
