Abstract: A novel and improved paper clip is formed from a single length of resilient metal wire bent into a configuration, having additional series of re-entrant loops. The upper loops are closely grouped together reducing the length of the arms, which allow stronger gripping force to be concentrated on the clamping jaws. The lower loops interconnecting the length-reduced arms form additional number of clamping jaws, which significantly add further holding strength. These particular features result in practical advantages in that the paper clip of the present invention provides a firm gripping force to effectively hold sheets of paper together without slipping or shifting; and does not create a large bulk in one area to make the pile unmanageable due to its flat form, and does not waste space in drawers and boxes as the upper loops are closely grouped together, and is simple and inexpensive to manufacture.
