A catheter having a proximal end provided with a nonreturn valve consisting of the catheter tubing end and of a rigid insert body whose rearward end is fixed in the catheter tubing. Bypass channels extend passed the end. The front end of the insert body is a cylindrical plug whose peripheral surface is joined by the catheter end acting as a valve hose. In case of overpressure in the catheter tubing, the tubing end is lifted from the plug and the pressure medium may escape accordingly.
