摘要：
A spring assembly for an administering device includes a driving spring configured as a spiral spring and a spring shaft. An inner end of the spring is rotationally fixedly attached to the spring shaft. A spring sleeve extends around the circumferential region of the spring, wherein the outer end of the spring is connected to the spring sleeve in a rotationally fixed manner and a disk-type spring-sleeve cover is attached to the spring sleeve or the spring shaft. The flange and the spring-sleeve cover extend radially away from an axis of the spring shaft and the flange is arranged near a distal end of the spring shaft. A radial stop is arranged on the flange periphery, and a blocking element is arranged on the spring sleeve to be complementary to the radial stop for releasably rotationally securing to each other when the blocking element and the radial stop engage.
