Abstract
Abstract A holder for electrical lamps with a first glass base cap, in particular for small lamps, which comprises a cup-like body of insulating material, and two contact strips inserted in the cuplike body. The two contact strips include a section projecting from the holder body and serving the electrical connection. Two resilient legs extend in about the longitudinal axis of the holder. The resilient legs are angularly bent substantially 90* relative to the first section within the range of the glass base cap to be held between the resilient legs. The first section of each of the contract strips has a longitudinal slot extending therethrough up to the connecting stay, and the entire contact strip is of increased material strength, the first sections projecting from the holder body constitute a plug for a socket sleeve.
