The invention relates to a flexible joint intended to connect two parts with each other, the connected parts might be rigid, of hose type or a combination thereof and are for instance of the pipe type used in vacuum cleaners, in which case the joint is intended to be placed between the rigid pipe member that is connected to the nozzle of the vacuum cleaner and the hose that is connected of the vacuum cleaner machine itself, which joint comprises: a plurality of ball joints (3-6), which co-operate with each other and which make possible for the joint to bend from a position, where the two parts and the joints that connects the two parts are essentially horizontally directed, two positions, where one of the parts (1) form an angle ( alpha ) with the other part; and a member (16) which is displaceable inside the ball joints (3-6) to different positions in relation to these, said member being able to go into engagement with and lock one or several of the ball joints (3-6). According to the invention, a flexible envelop (18) is applied on the outside of the ball joints (3-6), which envelop (18) is arranged to cover the areas between the ball joints (3-6).
