A joining member (10) is provided for connecting a first mesh cable tray element (1) to a second, longitudinally adjacent mesh cable tray element (2) and includes: a first plate portion (11) with first apertures (13, 14) formed therein for fixing the said first plate portion to vertical arms (7) of transverse wires (5a, 5b, 5c) and/or to side longitudinal wires (3b) of the two mesh tray elements (1, 2); and a second plate portion (12), substantially perpendicular to the first portion (11), with second apertures (15, 16) formed therein for fixing the said second plate portion to bottom portions (6) of the transverse wires (5a, 5b, 5c) and/or to bottom longitudinal wires. (3c) of the two mesh tray elements (1, 2). In a variant of the invention, the joining member (10') enables a first mesh tray element (1) to be connected to a second, longitudinally adjacent channel-like cable duct element (102). IMAGE
