Claim:
A connector configured to join two sections of coil tubing, comprising: a generally cylindrical main body having a mid-section and opposing ends; at least one pair of varying width circular grooves formed in the mid-section of the main body adjacent to one of opposing ends of the main body; and at least one pair of varying width circular grooves formed in the mid-section of the main body adjacent to the other opposing end of the main body; wherein each varying width groove is formed in one or more exterior surfaces of the mid-section, and wherein each varying width circular groove comprises: a varying outermost width that diverges from a narrow portion to a wide portion; a shallow depth portion; a deep depth portion that is deeper than said shallow depth portion and that comprises a bottom most portion, wherein the bottom most portion is angularly offset about a centerline of said connector relative to another of said bottom most portions of an adjacent one of said varying width grooves; and wherein each of said varying width grooves defines a center of curvature that is offset from said centerline of said connector.
