The present invention concerns a fluid transfer device for transferring fluid from a first fluid container to a second fluid container such as a piercing member protection device. The fluid transfer device comprises a longitudinal axis A, a first connection part comprising connection means for connecting to said first fluid container. The fluid transfer device further comprises a second connection part rotably mounted to the first connection part by mounting means, the second connection part further comprises connection means for connecting said second fluid container. The mounting means enable turning of said second connection part with respect to said first connection part. The present invention effectively allows a user to safely turn e.g. a syringe after assembly to read a volume indication or similar.
