There is provided an in-line regulator for pressurized fluids. The regulator comprises a regulator sleeve disposed in a tubular, fluid-carrying line or in constituent parts of the line and is provided with at least one wall orifice through which the line or the constituent part of the line communicates with the outside. The sleeve is constituted by two flange-like end portions fitting the tubular line and a central portion connecting the flange-like portions and having smaller outside dimensions than the flange-like portions, in such a way as to define, in conjunction with the flange-like portions and with the inside wall of the tubular line, an annular output space. The central portion is elastically deformable by an inflatory force and the annular output space communicates with the inside of the tubular line via at least one constant-cross-section opening in at least one of the portions, and with the outside via the wall orifice.
