A cable tray comprises a sheet metal central spine (10), comprising a channel web (12) and two channel flanges (13), and a plurality of cantilever bearer elements (11). Each bearer element is affixed to the spine by a spring clip (22) comprising two resilient tongues (23) adapted to clasp the spine between themselves. Each tongue has a barb formation (24) at its free end overlying a margin of the web, and a stud (25) extending into a hole (14) in the adjacent flange.
