The confinement of a relativistic cooling jet by the pressure and inertia of a surrounding matter is considered. It is demonstrated that, under certain conditions, even modest radiative losses behind the reconfinement shock can lead to a substantial focusing of the jet. The applications to blazars and M87 are discussed. Emphasize is given to the possibility that these recollimation nozzles may be the sources of the highly variable radiation observed in those objects.
