Abstract

The suction tube has an outer tube and an inner tube with latching recesses for engagement by a spring-loaded, manually released outer tube coupling latching element. A third tube encloses the outer tube telescopically; these tubes are releasably coupled in the extended state near their ends, where a seal closes the gap between them. The suction tube has an outer tube (3) and an inner tube (2) with latching recesses for engagement by a spring-loaded, manually released outer tube coupling latching element. A third tube (4) encloses the outer tube telescopically; these tubes are releasably coupled in the extended state near their ends, where a seal (3b,4b) closes the gap between them. The internal cross-section of the outer tube at the level of the seal and locking element is equal to or greater than the smallest cross-section of the suction tube. The length of the three tubes is between 420 and 570 mm. in the retracted state and between 890 and 1230 mm. in the fully deployed state.
