A hose dispenser comprises a rotatably-mounted cylindrical reel 10 for holding a length of hose 12 and an arm 16 which bears against a portion of the hose and is operatively connected to a braking device 30, the arm being movable from a position in which it causes the braking device to retard rotation of the reel to one in which it causes the braking device to allow rotation of the reel. The arm may be pivotally 26 mounted. A guide portion in the form of a channel or tube 18 through which the hose passes may be provided on the arm. The free end 22 of the hose may comprise a frusto-conical hood 20 which may lockably engage with the guide portion. The braking device may be adapted so as to allow rotation of the reel when a tension is applied to the hose, such as by pulling on the free end. In use, the hose may be connected to a supply of breathable gas and is especially suited for use by an operative working in an incident area or confined space.
