摘要： The invention pertains to a telescopic vacuum cleaner suction tube (1) with an outer tube (2), an inner tube (3) with snap-in depressions (7) that is telescopically arranged in the outer tube, an antitwisting mechanism (4d; 16) and an interlocking device with a snap-in element (15) that is disengaged from a snap-in depression (7) by an actuating element (5) situated about diametrically opposite thereof, wherein the interlocking device consists of a bow spring (6) that positively encompasses at least the inner tube (3) and once again engages the snap-in element (15) into the nearest snap-in depression (7) of the inner tube (3) in the telescoping direction under the prestress of a spring. The invention aims to develop a telescopic vacuum cleaner suction tube of the initially cited type that significantly lowers the manufacturing and assembly expenditures of the interlocking device and ensures that the tubes are always securely interlocked and able to withstand shock-like compressive forces, namely while simultaneously providing for an ergonomic handling.

摘要： A vacuum-cleaner pipe has an inner tube telescopingly received in an enlarged end of an outer tube. A retaining element diametrically opposite a slider which can be operated by the user can be received in an annular space between the tubes and on opposite sides of a guide body around which, in at least a partial turn, extends a bar spring which is braced against the guide body and not only provides the bias to the retaining element in the direction in which it presses a detent into a selected recess of a detent strip of the inner tube, but also forms the coupling between the slider and the retaining element so that upon movement of the slider in one direction, the retaining element is moved in the opposite direction.
