A housing assembly for a mobile telephone comprises a window panel and a front cover, with a clip arrangement which assists in preventing the common problem of the window panel falling out of the front cover. The clip arrangement comprises a rigid clip on the window panel which engages with a beam integrally moulded in the cover. This allows use of a low profile clip which does not extend into the telephone assembly, so permitting strong connections to be made in small assemblies.
