Abstract
A connector providing methods and apparatus for connecting two lengths of composite coiled tubing whereby the connector can be spooled with the tubing onto a reel. Embodiments of the connector include female and male housings which join together to create the coiled tubing connection providing mechanical and electrical or fiber optic connectivity between the two lengths of tubing. A connecting member on the male housing connectably engages the female housing. Splines on the male housing also align with corresponding flutes on the female housing. The female and male housings each attach to end portions of coiled tubing through a clamped connection and with the housings and connecting member being substantially flush with the outside diameter of the coiled tubing.
