Abstract
A connector for a coiled tubing end anchors internally and seals externally. The anchor profile is split with a gap to clear an internal spline without need to remove the spline to allow a seal to enter the coiled tubing since the seal is mounted internally to a sleeve that envelops the end of the coiled tubing. Component relative rotation extends the internal anchor radially against the coiled tubing inner wall to secure the connection with the seal engaged to the coiled tubing outer wall.
