Filling connector for a pressurised fluid container intended to cooperate with a filling outlet in order to allow said container to be filled, the connector comprising a body defining an internal filling circuit between an upstream end intended to be connected to a filling outlet and a downstream end intended to be connected to a container, the connector comprising an isolation valve that can move relative to a seat between an upstream position, in which the circuit is closed, and a downstream position, in which the circuit is open, said isolation valve being urged into its upstream position by a return member, the connector further comprising a dustscreen valve (10, 100) arranged upstream of the isolation valve, said dustscreen valve (10, 100) comprising a downstream end and being able to move, relative to the body, between an upstream position, in which the upstream end of the circuit is closed, and a downstream position, in which the upstream end of the circuit is open, said dustscreen valve (10, 100) being urged into its upstream position by at least one return member (14, 140), characterised in that the dustscreen valve (10, 100) can be selectively moved downstream either: - in a first set downstream position, called "contactless" position, which opens the upstream end of the circuit, in which the downstream end of the dustscreen valve (10, 100) does not push the upstream end of the isolation valve, the upstream end of the isolation valve being able to be pushed into its downstream position, in which the circuit is open, by pressurised fluid entering through the open upstream end of the circuit, or: - in a second set downstream position, called "contact" position, which opens the upstream end of the circuit, in which the downstream end of the dustscreen valve (10, 100) pushes an upstream end of the movable isolation valve in order to move the isolation valve, by means of contact, into its downstream position, in which the circuit is open, and in that the dustscreen valve (10, 100) comprises one or more passage(s) for guiding at least part of the flow of fluid moving from upstream to downstream through the body of said dustscreen valve, and in that the dustscreen valve (10, 100) comprises a first and a second concentric parts able to be moved in relation to one another in the upstream-downstream direction. - in a first set downstream position, called "contactless" position, which opens the upstream end of the circuit, in which the downstream end of the dustscreen valve (10, 100) does not push the upstream end of the isolation valve, the upstream end of the isolation valve being able to be pushed into its downstream position, in which the circuit is open, by pressurised fluid entering through the open upstream end of the circuit, or: - in a second set downstream position, called "contact" position, which opens the upstream end of the circuit, in which the downstream end of the dustscreen valve (10, 100) pushes an upstream end of the movable isolation valve in order to move the isolation valve, by means of contact, into its downstream position, in which the circuit is open, and in that the dustscreen valve (10, 100) comprises one or more passage(s) for guiding at least part of the flow of fluid moving from upstream to downstream through the body of said dustscreen valve, and in that the dustscreen valve (10, 100) comprises a first and a second concentric parts able to be moved in relation to one another in the upstream-downstream direction.
