A coupling connector that is concentrically engageable about the adjacent ends of two corrugated tubes and includes a bendable strap member having at least one slot at one end thereof and a pawl at an opposite end and wherein the slot is formed with an enlarged end portion. Ratchet teeth are disposed on the interior surface of the strap member along each side of the slot so that engagement of the pawl and ratchet teeth, to secure the connector about the adjacent tube ends, occurs upon insertion of the pawl through the enlarged end portion of the slot.
