A sleeve joint for connection of a pipe (P) with a threaded end (T) using a counter-threaded ring nut (N). The sleeve joint has a tubular body (2) of elastomeric material, which is designed to be interposed between the ring nut (N) and the pipe (P) and an annular member (3) of rigid material, which is substantially coaxial with and integrally coupled to the tubular body (2) into a one-piece assembly. The annular member (3) further has a plurality of radially and inwardly directed laminar teeth (5, 5', 5", ...) which are susceptible of engaging the outer surface of the pipe (P) thereby exerting a mechanical holding action thereon against any relative motion of the pipe (P) and the threaded end (T).
