A pressure regulator having a housing which is formed from a hollow body closed by a cover piece which is made from one piece, with an inlet, an outlet and a valve seat, a regulator sleeve arranged within the housing and defining a flow channel from an upstream end adapted for cooperating with the valve seat towards a downstream end associated with the outlet, a spring biasing the regulator sleeve towards the outlet, the downstream end of the flow channel tapering outwardly, wherein a guiding insert is provided at the upstream side of the housing in a recess of the cover piece, the guiding insert being associated with a seal adapted for slidably contacting the regulator sleeve and wherein the recess of the cover piece is provided with a protrusion behind which the guiding insert is engaged such that the guiding insert is arranged between the protrusion and a bottom surface of the recess wherein the protrusion constitutes a single deliberate narrowing of the recess in the cover piece and the guiding insert is in direct contact with the protrusion and is fixed to the cover piece merely by means of the protrusion.
