This screened connector for electrical conductors includes paired connector assemblies, namely a first connector assembly and a second connector assembly, the connector assemblies including an insulating body made of a molded material incorporating respectively male and female contacts, for mechanical fastening and electrical connection of contact terminals provided at the ends of the conductors to be connected, and a screening case that surrounds the insulator body. Each screening case has the general shape of a hollow cylinder internally defining a continuous passage so that the insulator bodies are in contact with each other via a seal.
