A retractable barrier system comprises a support member, for example in the form of a housing ( 10 ), a spool ( 14 ) supported for rotation by the support member, a spring ( 34 ) adapted to apply a biassing load to the spool ( 14 ), and a skirt ( 30 ) arranged to deflect water away from or around the spring ( 34 ) thereby reducing the quantity of water impinging, in use, on the spring ( 34 ) and reducing corrosion thereof.
