An apparatus for blocking a medium flow passage in a spray head has a blocking element in the passage that, when unbroken, blocks the passage of medium from a first side having a first pressure to a second side having a second pressure. A supporting element is on that side of the blocking element where the pressure is lower, the supporting element being movable between a first position where the supporting element supports the blocking element so that it cannot be ruptured and a second position where the supporting element does not so support the blocking element.
