ABSTRACT:
A protective casing (20) for a lamp holder (10) for outdoor use comprises a cylindrical part (21) and a bowl-shaped base part (22) which are made of a relatively soft, elastic material and can be clamped axially together around an ordinary lamp holder (10). The engagement faces between the two parts are formed with radial recesses (27), which together form a hole for the lead-in of a cable and are dimensioned so that the cable is fixed upon the clamping. This provides a seal for the cable lead-in and also tension relief of the cable. Due to the clamping, a sealing ring (25) for the lamp (14, 15) is fixed between an end edge of the holder (10) and a rim flange (26) of the cylindrical part (21).
