Zusammenfassung:	A mandrel (10) of simplified construction and reduced cross sectional size for connection in well tubing comprises a cylindrical body (16) defining a main bore (20) for passage of wire line tools therethrough. A longitudinal slot (30) is formed in the cylindrical body (16). A side pocket subassembly (34, 42, 50, and 52) is secured to the body (16) over the longitudinal slot (30) formed in the body. The slot (30) is sized to permit passage of pocket devices only from the main bore (20) through the offset chamber (44) and into the pocket (60). If desired, an orienting member (22) can be provided within the cylindrical body (16).
