A collapsible clothesline intended to be stored in situ in the ground and to be erected by water pressure. The clothesline comprises a casing intended to be located in a bore in the ground and a stem which is retractible into and extensible from the casing. The stem itself consists of an inner and an outer stem element, with the former being retractible downwardly into and extensible upwardly from the latter. A number of arms, linked by lines for supporting laundry, are pivoted to the other stem element and are connected by ties to the upper end of the inner stem element. When the inner stem element is extended from the outer stem element, with the other stem element already extended from the casing, the ties pull the arms up from a storage position, in which they lie alongside the stem, to a use position, in which they extend radially from the stem. The clothesline is erected by supplying water pressure to the casing interior and collapsed by relieving such pressure.
