Abstract: The present invention discloses a connecting clasp and a multi-disc optical disc cartridge using the connecting clasp for connection. The connecting clasp comprises two half bodies rotationally connecting with each other, wherein one half body can rotate around the other one at a degree from 0° to 180°. The multi-disc optical disc cartridge comprises multiple transparent disc sheets for accommodating optical discs. When the connecting clasp is used for connecting the multiple disc sheets, the two half bodies are inserted into the corresponding mounting sites of the adjacent disc sheets respectively so as to rotationally connect the disc sheets. Therefore, the adjacent disc sheets can rotate relative to each other at a degree from 0° to 180°, or even be displayed in the manner of turning pages at a degree from 0° to 360° when multiple disc sheets are connected together.
