Abstract
Disclosed is a spring clip formed by bending a single sheet of elastic metal plate which comprises: a base portion having an opening formed in a central portion thereof; a rising-up portion raised up substantially vertically from the base portion; and a grasping portion bent at an acute angle from the rising-up portion toward the base portion so as to cooperate with the base portion to grasp sheets of paper or the like between the grasping portion and the base portion, the grasping portion including a contact portion formed at a portion facing at least an outer circumferential portion of the opening of the base portion for contacting with the sheets of paper or the like, and a lead-in portion extended from the contact portion to a top end portion and bent so as to come away from the base portion. The attachment of the spring clip to the sheets of paper or the like can be performed easily only by making the base portion abut onto the back surface side of the sheets of paper or the like, and inserting the lead-in portion onto the sheets of paper or the like from the edge portion of the latter.
