Abstract: A discharge lamp is disclosed, which comprises a discharge vessel sealed in a tubular envelope. The lamp has a lamp base covering an end part of the envelope, and fixing means for providing a substantially rigid fixing of the envelope to the lamp base. The fixing means comprises a metal clamp ring, which surrounds a part of the envelope external to the lamp base. A melt plastic lining is provided between the clamp ring and the envelope. The melt plastic lining substantially completely fills a space between the envelope and the clamp ring. A method is also provided for manufacturing a discharge lamp as above. The method comprises the steps of providing a space between the clamp ring and the envelope, and providing a hot-melt plastic lining in the space between the clamp ring and the envelope. Subsequently, the plastic lining is melted, and substantially completely fills the space between the clamp ring and the envelope, establishing a tight and stable mechanical connection between the clamp ring and the envelope.
