Abstract
A spring clip having a pair of opposing flat holding members the leading ends of which are resiliently pressed against each other to clip sheets of paper or the like therebetween and opposing ear-like projections which extend widthwise from the side edges of the opposing holding member, respectively, and serve to open the leading ends of the holding members in cooperation with opening means of a special device for applicating clips. In contrast with a conventional spring clip of the same type, the disclosed clip has no levers pivoted to the leading ends of the holding members, which are used to open the leading ends of the holding members for the purpose of inserting therebetween the sheets to be clipped, and, therefore, is advantageous since the clipped sheets are not prevented by the levers from being turned up.
