Abstract
Abstract A suction line has a stiff suction tube and a flexible suction hose having a connecting end. A connector for connecting the connecting end of the flexible suction hose to the stiff suction tube to form the suction line having free ends is provided. One of the free ends of the suction line is connected to a vacuum source. The other free end of the suction line can receive a vacuuming tool. The stiff suction tube has a longitudinal axis. The connector is rotatable about an axis extending transverse to the longitudinal axis.
