The inside pipe wall of a telescopic vacuum cleaner suction pipe (10) having an outside pipe (11) and an inside pipe (12) has an impressed catch strip (17) with catch recesses (18), with which strip a catch element (35) interacts. The latter can be disengaged against the restoring force of a spring by means of a holding-down device (30) which is actuated by a sliding handle in the axial direction (x) of the pipe. The annular space (R) formed between a cylindrical end widening (13) of the outside pipe (11) and the inside pipe (12) is filled by a tubular guide element (16) for the holding-down device (30), sliding handle (28), catch element (35) and spring (19). The sliding handle (28) and catch strip (17) are arranged on two diametrically opposite circumferential positions of the vacuum cleaner suction pipe (10). …<??>A constructional simplification and ease of assembly of the vacuum cleaner suction pipe (10) result from the fact that the holding-down device (30) is arranged directly adjacent to the catch strip (17) inside the annular space (R) between the outside (11) and inside pipe (12), that the guide element (16) maintains tension on one end of a bar spring (19) which is wound at least partially around the guide element (16) inside the annular space (R) and couples the movement of the holding-down device (30) and the sliding handle (28), which penetrates the wall of the end widening (13). …<IMAGE>… |
