An hydraulic pressure master cylinder has a cylinder usually of metal, and a separately made plastics reservoir. The reservoir is retained on the cylinder by means of a pair of resilient arms, the internal faces of which are recessed to conform the external surface of the cylinder. The reservoir is fitted to the cylinder by deforming the arms outwardly to enable them to shap-engage around the cylinder so that the latter seats within the recesses. If desired, the free end portions of the arms may be joined by a fixing device such as a rivet.
