Abstract
In a socket for discharge lamps 10, having a tubular enclosure 22, a female terminal 23 is located in the center of the socket. A circular elastic sleeve 24 is mounted to the outside surface of the tubular enclosure. On the inside surface of the elastic sleeve 24, grooves 31 are formed fitting over the ribs 30 made on the outside surface of the tubular enclosure 22. A number of steps extending in a circumferential direction are formed on the surface 51, which comes in contact with the discharge lamp 100. The discharge lamp 100 can be easily removed for the replacement while the elastic sleeve 24 remains attached to the socket 10. The elastic sleeve 24 makes it possible to secure tight sealing after the discharge lamp has been replaced.
