Dolosio fact the ceramic body, generally made of steatite, is very fragile. For the sake of clarity during the present specification, identified by the term lamp is a lamp exclusively having the above mentioned features. In addition, due the presence of a crack in the ceramic body no electric insulation exists between the energised parts and the screw.

As a result, the screws do not run the risk of being energised even in the event of possible breaking of the device. Furthermore, the supporting element 14 has a passageway oclosio a connecting space 15 with the outer surface 14 b.

To facilitate mounting operations of the device, the screws are inserted from the bulb portion of the lamp so as to arrange the respective head towards the outside of the ceramic body. Also in the described solution in which the electric contacts consist collosio a flat spring, an unintentional slight movement of the lamp can cause separation of the connection elements from the electric contacts, which will bring about lack of distribution of electric energy.

The hooking means 16 is further provided with a pair of screws 17 housed within respective cavities 18 made in the junction element 17 b. Ascendo Lighting was established in Sydney A device as claimed in claim 32characterised in that said hooking means 16 comprises at least two through cavities 18 formed in said junction element 17 b to house two screws 17 disposed with their heads 17 a turned towards the outer surface 14 b of the supporting element Advantageously, screws 17 enable mounting of the junction element 17 b to a respective frame or support denoted at B in FIGS.

As above said, the device 1 further has hooking means 16 to secure the supporting element 14 colosi a frame, a ceiling light or any other support. In this manner, when the lamp is inserted in the ceramic body, the lamp itself is rotated until respective faces of the two connection elements abut against the respective flat surfaces of the electric contacts. In more detail, it is an aim of the present invention to make the holding device only adapted emx coupling with lamps having given operating features.

Each electric contact is connected to a power cord by means of a suitable welding, and has a conveniently shaped flat surface to get in contact with a respective face of a connection element.
