A connection system for connecting tubular members to each other includes a rotatable connector sleeve on one of the tubular members. A make-up tool has a curved rack of gear teeth that are engagable with the connector sleeve for causing rotation of the connector sleeve in unison with the rack. The make-up tool includes a power tool having a drive motor that rotates a drive shaft. A pinion gear mounted on the drive shaft engages the teeth of the rack to cause the rack to move in a rotational direction when the drive shaft is rotated. This movement causes the connector sleeve to rotate to make-up or break-out the connection.
