A pneumatic brake booster for a hydraulic motor vehicle brake system, having a booster housing which comprises a front housing shell and a rear housing shell, which are arranged in series along a central axis, having at least one connecting pin which is arranged extending axially in the booster housing in an axis-parallel fashion with respect to the central axis, supports the booster housing from the inside by two supporting formations, and projects with an end section through the booster housing from the inside to the outside on at least one side, wherein the housing shells are arranged such that they are each connected to the connecting pin in order to secure them against being pushed apart relatively in an axial direction,

• wherein the connection comprises at least one latching connection,
• wherein at least one of the front housing shell and the rear housing shell has a radially elastic formation which is latched in at an axial undercut on the connecting pin, and
