need a small part?

I have a recliner with a push button instead of a handle to activate the foot rest. The piece that attaches to the wire and the control has broken off the wire and cannot be forced open to reattach. It looks like a key without teeth with an open ring. The ring attaches to the control and the stem of the "key" attaches to the wire. With out this piece I cannot open the foot rest. Can someone help me find this part. Thank you
