ABSTRACT OF THE INVENTION A grapple connection for interconnecting coiled tubing with a well tool comprises first and second tapered split rings and a double-tapered intermdiate split ring enclosed in a cylindrical, threaded housing. When the housing is totated with threaded engagement of the housing to a compression ring and the well tool, the well tool and the compression ring bear against the spilt ring causing the tapered surfaces to press the grapples inwardly and the intermediate ring outwardly to effect a tight interconnection between the coiled tubing and the well too.
