A connection arrangement for transferring gas from a compressed gas cartridge, has a valve element configured to control the release of gas from the cartridge; a male outlet which is integral with the valve element; a male inlet of a gas receiver for a tool that runs on compressed gas; and a connector receiving and connecting the male inlet and outlet. The connector is a tubular housing having a through hole extending from one end to the other. An inner wall of the housing contacts side surfaces of the male outlet and inlet in a sealing manner. The connector also has, in a middle region, transverse sealing surfaces that contact the end faces of the male outlet and inlet. The diameter of the through hole in this middle region is the same as the inner diameters of the openings in the ends of the male inlet and outlet.
