An improved rotating spout lock joint sleeve comprised of a spout and a mounting sleeve at its bottom section, which is first inserted into a water supply base, with a lock joint sleeve pre-fitted onto the body of the spout utilized to form a continuum between its bottom section internal threads and the external threads at the top section of the water supply base, the features of which include the following. The opening of the lock joint sleeve is sufficiently enlarged to accommodate the insertion of the mouth at the anterior extremity of the spout, thereby enabling continuity between the bottom section of the spout and the mounting sleeve top edge. A stepped neck is crimped onto the lower section of the mounting sleeve such that when a mounting ring is placed against its lower extent, the mounting ring is at the same time against the bottom edge of the stepped section at the middle section inside the lock joint sleeve, enabling the initial coupling of the lock joint sleeve to the mounting sleeve outer circumference as well as the convenient and rapid fastening to the external threads at the top section of the water supply base. As such, the structure of the present invention provides for the secure assembly of the spout to the mounting sleeve, thereby achieving convenient fabrication, assembly, and installation that averts dislodging and prevents the abrasion of the spout surface.
