A socket box housing has an aperture 40 in a side wall 10 capable of removably receiving a blanking cover or a first insertion portion 21 of a tubular trunking insert 20. Portion 21 and the cover each carry connecting elements 51, 52, 53 for cooperation with side wall 10 and aperture 40. The other end of the trunking insert is received in use by one end of a length of trunking. Aperture 40 has recessed edges 13a, 14a, 15a and the connecting elements are in the form of detents which displace laterally upon insertion in the aperture 40 to pass these edges and snap back behind them to retain the cover or insert 20 in position, as the case may be. <IMAGE> |
