The invention relates to a receiving sleeve for a piezoelectric actuator, in particular for a piezoelectric actuator for driving an injector of an injection system in an internal combustion engine. Said sleeve comprises a first sleeve part (1) and a second sleeve part (2), the first sleeve part (1) being connected to the second sleeve part (2) when the sleeve is assembled. In addition, the inventive receiving sleeve comprises an anti-rotation element (6, 8) for maintaining a predefined angular position between the first sleeve part (1) and the second sleeve part (2).
