The central part (12) of the cover has a sinusoidal shape with the lower end (13) carrying a fastening peg (4) and the upper end (14) attached to a horizontal bar (15). The ends of the horizontal bar are attached to two rigid side arms (16, 17) extending down to the same level as the central portion (12). The free ends (18, 19) of the side arms have inwardly projecting feet with holes (22, 23) bored through them. In cross section the peg (4) has a shoulder at the free end and a neck portion which holds a retaining stirrup fitted around the body of the relay which the cover fits over.</p> |
