Abstract: This invention provides a device for connecting electrical conductors, portions of which can be used as both a receptacle and as a mating connector for joining conductors of an electrical circuit. The device has an insulating body with a passageway extending therethrough from a front end to a rear end. An electrically conductive sleeve is inserted into the passageway, wherein the sleeve is locked and held by abutments formed in the passageway. The sleeve has a resilient electrical contact and serves as a female contact, receiving a mating male contact member. Alternatively the support end of a connector element can be inserted into the sleeve, converting it into a male contact which can be inserted into an insulating body identical to the firstmentioned insulating body to form a plug-type electrical connector. Attachment means, such as a soldering sleeve, is provided on one end of the sleeve for connecting the sleeve to an electrical circuit.
