A device and a method are provided, for shrinking a protective element (101) shrinkable by means of the supply of heat onto an optical waveguide (100). The method involves generating thermal radiation, reflecting it and focusing it onto a focus zone in which the protective element (101) is held. The device contains a heating element (10), which generates thermal radiation, a reflector (30), which focuses the thermal radiation emitted by the heating element onto the focus zone, and a mount (20), by means of which the protective element (101) can be held in the focus zone.
