ABSTRACT:
A tube coupling for use in a vacuum cleaner includes a first tubular part and a second tubular part, which parts can be coupled to and separated from one another. The first part includes a locking member which is movable from a first position, in which the locking member locks the second part relative to the first part, to a second position, in which the locking member releases the second part. The first part further comprises a slide which cooperates with the locking member, the locking member being moved to the second position if the slide is moved parallel to a longitudinal axis of the first part in a direction away from the second part. In this way, a force exerted on the slide to unlock the parts and a force exerted on the first part to separate the parts from one another are oriented in the same direction, as a result of which the tube coupling is very easy to handle. In a special embodiment the slide of the tube coupling is a grip held by the user when the parts are to be uncoupled. The user then exerts both the force necessary to unlock the parts and the force necessary to separate the parts on the slide, so that the parts are separable by one continuous movement of the hand of the user.
