    Abstract: A suction hose for vacuum cleaner includes a tubular inner part, a jacket part and a locking device. The inner part is variable in length and includes a hose wall having a coil spring integrated therein, the coil spring being configured to automatically return the inner part from an extended position to a shortened position. The jacket part is configured to completely receive the inner part when the inner part is in the shortened position, the jacket part including a tubular shape. The locking device is configured to fix the inner part, in the shortened position, in the jacket part. The locking device includes a tubular member configured to surround the inner part, the tubular member including a first part of a first snap-fit device configured to cooperate with the jacket part so as to connect the tubular member and the jacket part.
