This is what you need to have in your loaded swf:

function lHandler(e:Event):void
{
var myClip:MovieClip = e.currentTarget.parent as MovieClip;
if(MovieClip(myClip.parent.parent.root) != null)
{
MovieClip(myClip.parent.parent.root).removeChild(L oader(myClip.parent.parent));
}
}
termini.mc1.addEventListener(MouseEvent.CLICK, lHandler);
