Abstract
A retractable hose reel assembly comprises a reel (2) rotatably mounted in a casing (1) and a torsion spring (8) for rotating the reel in a direction corresponding to winding of the hose on the reel (2). A ratchet (14) and pawl (18) prevent or limit rotational movement of the reel (2) in the winding direction. A lever (20) is manually movable to a locking position in which unwinding movement of the reel (2) is prevented, for example to prevent vandalism or to prevent a child pulling the hose from the reel and suffering discomfort or injury as a result of retraction of the hose by the spring (8).
