The present invention relates to a double clip for office use comprising a clip main body of metal spring sheet bent into an isosceles triangular cross-section, and operating levers of metal wire tiltably and pivotally connected to the clip main body so as to open the apex against the spring force, wherein index caps of synthetic resin serving as knobs are removably fitted on the bent front ends of the levers, thereby providing the double clip itself with an index indicating function in connection with filing and subsequent withdrawal of documents to facilitate the handling of documents while using the index caps as knobs to open and close the clip main body without giving pain to the finger tips of the user.
