1. A pulsation damper for damping pressure medium vibrations in a slip-controlled motor vehicle brake system comprising:
a membrane within a bore of a housing, wherein membrane is exposed to the pressure medium on one side and faces a gas-filled cavity inside the housing on an opposing side, wherein the membrane is cup-shaped and has at least one of grooves and ribs defined on the circumference thereof; and
a cup-shaped plug to close the bore of the housing, wherein the membrane and the plug form an independently handleable, functionally pre-testable assembly, wherein the membrane has a sleeve-shaped extension which completely encloses a tubular section of the plug along its outer circumference; and
a plurality of ribs run in the longitudinal direction on the circumference of the membrane between the tubular section and the cup-shaped region of the membrane.
