- Such devices are also referred to as telescopic spray lances.
- a liquid such as a cleaning or decontamination fluid
- the spray tube several telescopically slidable and extendable if necessary pipe sections.
- an outlet for the liquid is arranged.
- the outlet may be formed, for example, in the form of a nozzle with which the liquid can be dispensed as a spot jet or as a fanned-out jet.
- An outlet hose is connected to the outlet, which is passed through the spray tube and emerges from the spray tube at the rear end of the spray tube.

- a device of the type mentioned is known from DE 36 26 997 AI.
- the actuator is in this case held on laterally projecting from the spray tube support elements at the rear end portion of the spray tube.
- the actuating device On its front side facing the front end of the spray tube, the actuating device has a connection element to which the supply hose can be connected, and at the front end of the spray pipe facing away from the back, the actuating device has a connection element for the outlet hose.
- the effective length of the spray pipe can be changed by the user, however, the handling of the device, when the pipe sections are maximally pulled apart difficult.
- Object of the present invention is to develop a device of the generic type such that it has a simpler handling.
- the user can adjust the axial position of the actuator relative to the spray pipe to the respective application, in particular he can choose a different position for the actuator at maximum pulled-pipe sections as in maximally telescoped pipe sections.
- the actuating device is held steplessly adjustable on the pipe section in the axial direction.
- the user no specific axial positions of the actuator are specified, but the user can choose the axial position of the actuator relative to the pipe section within an adjustment range freely.
- the adjustment range may in this case extend practically over the entire length of the pipe section or over a portion of the pipe section, which serves to hold the actuator.
- the actuating device can not only be adjusted in the axial direction but can additionally be rotated about the longitudinal axis of the pipe section.
- Such a configuration is particularly advantageous when the spray tube is inclined at the front end to the longitudinal axis or when the outlet is defined by a nozzle body inclined to the longitudinal axis of the spray tube. The user can then choose depending on the purpose of the angular position and the axial position of the actuator relative to the angled end portion of the spray tube or the angled nozzle body.

- the user can pivot the clamping lever in the release position, so that he can then adjust the actuator relative to the pipe section.
- the user can then pivot the clamping lever in the clamping position. This has the consequence that the actuator is clamped to the pipe section.
- the handling of the device according to the invention can be further simplified by the clamping lever is aligned in its clamping position parallel to the longitudinal axis of the pipe section.
- the size of the actuator including the clamping device in the clamping position of the clamping lever can be kept low.
- Starting from its parallel to the longitudinal axis of the pipe section aligned clamping position of the clamping lever can be pivoted in an obliquely or perpendicular to the longitudinal axis of the pipe section aligned release position.
- the clamping lever can interact via transmission elements with a clamping member by means of which the actuating device can be clamped to the pipe section.
- the clamping lever has an eccentric to the pivot axis arranged clamping cam.
- the actuator can be clamped to the pipe section. Additional clamping devices can be omitted. This facilitates the manufacture and assembly of the clamping device and extends their life.
- the clamping lever is integrally connected to the clamping cam.
- Clamping lever and clamping cam can be formed, for example, as a one-piece plastic molding. It is particularly advantageous if the clamping cam has a clamping surface, which in the clamping position of the clamping lever is positively clamped to the outside of the pipe section can be applied.
- the pipe section may for example be designed cylindrical and the clamping surface may form a partial cylinder, which can be applied in the clamping position to the outside of the pipe section.
- the positive engagement of the clamping surface of the clamping cam pivotable together with the clamping lever causes a locking of the clamping lever in the clamping position.
- the locking effect is enhanced if an elastically deformable clamping element is arranged in the region of the clamping surface.
- the clamping element may for example be designed in the form of an elastically deformable lining or in the form of a sealing ring, in particular an O-ring, which surrounds the clamping cam in the circumferential direction.

It is advantageous if both the first connection element and the second connection element are arranged at a rear side of the actuating device facing away from the front end of the spray tube. This results in a further simplification of the device according to the invention, because both the supply hose and the outlet hose extend in the rear area of the actuating device due to the rear-side arrangement of the connecting elements. The risk that the user is hindered by the use of the device through one of the hoses, this can be kept low.
