Abstract
A spoolable connector which connects two opposing sections of coil tubing so as to transmit load between one section of coil tubing and another section of coil tubing. The spoolable connector has opposing non-circular grooves into which portions of the sections of coil tubing are deformed so as to create the torque transmitting connection between the spoolable connector and sections of coil tubing. The spoolable connector also includes a plurality of parallel radial slots on each opposing end to enhance bending of the connector at the ends as well as a plurality of longitudinal slots at each end to accommodate the weld seam line in the coil tubing. Seals may be installed as a sleeve which in use fits over the mid-section of the connector.
