Abstract: In a clip, a pair of clip piece portions 1 and 2 bent in the same direction from two bent portions 4-1 and 4-2 of a bent proximal end portion 4 are formed, the two clip piece portions 1 and 2 are kept in contact with each other with a predetermined clamping force, an opening/closing operating portion 3 having an outward curve shape in cross section and projecting returnably to be elastically deformable inwardly and outwardly is formed on one of the two clip piece portions 1 and 2, the opening/closing operating portion 3 is pushed and deformed inwardly so that open ends of the two clip piece portions 1 and 2 are sprung away in a direction to be apart from each other by an elastic spring-back force applied to the opening/closing projection 3, and an opening projection 5 for increasing an opening on the open end sides of the two clip piece portions 1 and 2 is further provided in a portion in the vicinity of the opening/closing operating portion 3 on the open end sides of the two clip piece portions 1 and 2.

Abstract: A clip body having upper and lower clamping pieces which flare continuously and from both ends of a bending portion in a desired width and a pressing cover having upper and lower clamping pieces continuously extending from both ends of a bending portion which is formed so as to provide a desired width, in which tops of the upper and lower clamping pieces are to be engaged with upper and lower parts close to the bending portion of said clip body, and a width formed between the tops being narrower than the maximum width formed between the upper and lower clamping portions of the clip body and wherein the pressing cover being slidably provided on the outer portions of the clip body so that both the upper and lower clamping pieces of the clip body approach each other in a pressing state.
