Claim:
1. A closure element for a valve device for fluids, the closure element comprising: a membrane; and a locking member protruding from the membrane, said locking member having an outer diameter recess; wherein the outer diameter recess has a stop region toward a distal end of the locking member; wherein the outer diameter recess is configured to lock the locking member by means of engaging locking slides in the outer diameter recess; wherein the locking slides are movable in a direction substantially orthogonal to a feed axis of the locking member; wherein the outer diameter recess is spaced apart from the membrane so that the locking slides are displaceable by a coupling socket in a locking region of a compressor from radially outwardly into a locking position in which the locking slides engage in the outer diameter recess; wherein the compressor comprises a pressing region to move said membrane toward a valve seat and to press the membrane against said valve seat; wherein the locking region faces away from the pressing region of the compressor, and wherein the coupling socket embraces the compressor to displace the locking slides so that the locking slides assume the locking position in which the locking slides engage in the outer diameter recess; and wherein the locking slides engage in the outer diameter recess on the stop region in order to pull the locking member and the entire closure element by means of the locking slides in a direction away from the valve seat in order to open the valve device.
