ABSTRACT:
An internal slip-type connector for coupling coiled tubing to tools or other coiled tubing having a body that does not upset the outside diameter of the coiled tubing with seal means to seal to the inside of the coiled tubing. A mandrel is threadably engaged to the inside of the end of the body and slip means abuts the first end of the body and engages the mandrel. Rotation of the body relative to the mandrel wedges the slip means into the inside of the coiled tubing for gripping.
