Abstract
A pressure-effected interconnection of a metal part and a plastic part which is slipped over the metal part with a press fit, in particular in a fuel injector for internal combustion engines, is provided in which, for a reliable connection between the pressing pieces, without high demands on manufacturing tolerances, the outer wall of the metal part has circumferential ribs disposed one behind the other in the axial direction, with a back that rises from the outer wall towards the outside in the slide-on direction of the plastic part, and a flank that falls steeply from the back to the outer wall. Each rib has disposed in front of it—viewed in the slide-on direction of the plastic part—an annular groove, the annular groove being introduced into the outer wall, directly at the foot of the back.
