The present invention is a combination of a curtain clip and a curtain slide. The curtain clip includes a socket portion connected to a tab portion. The socket portion has a socket for receiving the ring of the curtain slide when the socket and ring are urged together. Resilient fingers in the clip socket define a slot for receiving the ring shank of the ring of the curtain slide. The body of the curtain clip has a tab portion for fastening to a curtain, either by sewing the tab to curtain, or inserting the tab portion in a pocket in the curtain.
