Ringed staple ( 1 ), or staple that when closed takes the approximate form of a ring, that presents a cross-section ( 3 ) with a substantially straight part ( 6 ) and a non-straight part ( 5 ), preferably curved circular. The non-straight part ( 5 ) corresponds with the exterior area ( 14 ) of the staple ( 1 ), whereas the substantially straight part ( 6 ) corresponds with the interior area ( 13 ) of the staple ( 1 ). The staple ( 1 ) requires less material and provides certain improved features than conventional staples ( 8, 10 ) with a substantially circular cross-section ( 9 ) or a substantially rectangular cross section ( 11 ).
