A master cylinder (10) for a hydraulic vehicle braking system has a housing (12) with a bore (14) formed therein, in which bore a first piston (24) and a second piston (26), which is arranged at an axial distance from the first piston, are guided in a sealing and displaceable manner. A restraining device (40) for a return spring (38) of the first piston (24) is arranged between the first piston (24) and the second piston (26), which device prevents the return spring (38) from being compressed and expanded beyond a certain extent. In order to simplify the structure and assembly of the restraining device (40), the latter consists of a first, substantially sleeve-shaped component (42) and a second, substantially pin-shaped component (44) which is connected to the first component such that it can be disengaged and which comprises at its end which faces the sleeve-shaped component (42) a flange (46) which projects radially outwards. The sleeve-shaped component (42) comprises at its associated end a first, U-shaped receiving flange (52) which projects radially inwards and which positively interacts with the flange (46) on the pin-shaped component (44) such that the two components (42, 44) cannot move apart in the axial direction. In order to introduce the flange (46) laterally into the sleeve-shaped component, the latter is provided in its circumferential surface area with an introduction opening (54) which communicates with the open region of the U-shaped receiving flange (52).
