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 can comprise a longitudinal axis A and a first connection part comprising a connector that connects to the first fluid container. The fluid transfer device can further comprise a second connection part rotatably mounted to the first connection part by a mounting element, and the second connection part can further comprise a threaded coupling that connects the second fluid container. The mounting element can enable turning of the second connection part with respect to the first connection part. Such a device can allow a user to safely turn e.g., a syringe after assembly to read a volume indication or similar.

1. A fluid transfer device for transferring fluid from a first fluid container to a second fluid container, said fluid transfer device comprising a longitudinal axis and a first connection part comprising a connector that connects to said first fluid container, wherein said fluid transfer device further comprises a second connection part rotatably mounted to said first connection part by a mounting element, wherein said second connection part comprises a threaded coupling element that connects to said second fluid container, wherein said fluid transfer device is further arranged with at least one protrusion, wherein said at least one protrusion substantially prevents said first connection part from turning in a predetermined direction with respect to said second connection part thereby enabling assembly with said first fluid container, while still allowing said first connection part to turn in a direction opposite of said predetermined direction thereby preventing disassembly with said first fluid container, wherein said first connection part is provided with a flexible barrier member for providing a leakage seal. 2. A fluid transfer device according to claim 1, wherein said device is a piercing member protection device. 3. A fluid transfer device according to claim 2, wherein said piercing member protection device comprises a piercing member protection part comprising a protection chamber adapted to protect a piercing member, said piercing member protection device having a secured position in which at least the tip of said piercing member is enclosed within said protection chamber of said piercing member protection part so as to prevent said tip of said piercing member from exposure, and an unsecured position in which said tip of the piercing member is arranged outside the protection chamber of said piercing member protection part. 4. A fluid transfer device according to claim 2, wherein said piercing member protection device is a medical piercing member protection device. 5. A fluid transfer device according to claim 1, wherein said at least one protrusion on said fluid transfer device enables at least a 90° turn. 6. A fluid transfer device according to claim 1, wherein said mounting element comprises a locking groove arranged transversally to the longitudinal axis around the periphery of a mounting part that connects to said piercing member protection part. 7. A fluid transfer device according to claim 1, wherein said fluid transfer device further comprises a piercing member. 8. A fluid transfer device according to claim 7, wherein said fluid transfer device further comprises a stabilization member arranged to stabilize said piercing member. 9. A fluid transfer device according to claim 8, wherein said stabilization member comprises a hollow tube arranged along the longitudinal axis or parallel thereto, wherein said hollow tube is arranged to at least partly enclose said piercing member. 10. A fluid transfer device according to claim 9, wherein said at least one protrusion engages at least one interacting protrusion element on said first connection part. 11. A fluid transfer device according claim 1, wherein the first connection part and the second connection part have two positions, one position in which the at least one protrusion is engaged so as to prevent turning of the first connection part with respect to the second connection part in a predetermined direction, and one position in which the first connection part may be turned in any direction with respect to the second connection part. 12. A fluid transfer device according to claim 11, wherein said two positions are enabled by a play between the first connection part and the second connection part. 13. A fluid transfer device according to claim 1, wherein said threaded coupling element on said second connection part interacts with said at least one protrusion so that said predetermined direction in which said first connection part is prevented from turning with respect to said second connection part is the same direction as said second connection part is turned in order to connect a second fluid container thereto. 14. A fluid transfer device according to claim 1, wherein said connector on said first connection part interacts with said at least one protrusion so that said predetermined direction in which said first connection part is prevented from turning with respect to said second connection part is the same direction as said second connection part is turned in order to connect a first fluid container thereto. 15. A fluid transfer device according to claim 1, wherein said connector is a neck element comprising two guiding members. 16. A fluid transfer device according to claim 1, wherein said connector is a threaded coupling. 17. A fluid transfer device according to claim 1, wherein said mounting element comprises a cylinder shaped extension of the first connection part which at least partly encloses the second connection part. 18. A fluid transfer device according to claim 1, wherein said at least one protrusion comprises a plurality of saw tooth protrusions. 19. A fluid transfer device according to claim 1, wherein said at least one protrusion comprises a plurality of sinusoidal shaped protrusions. 20. A fluid transfer device for transferring fluid from a first fluid container to a second fluid container, said fluid transfer device comprising a longitudinal axis and a first connection part comprising a connector that connects to said first fluid container, wherein said fluid transfer device further comprises a second connection part rotatably mounted to said first connection part by a mounting element, wherein said second connection part comprises a coupling element that connects to said second fluid container, wherein said fluid transfer device is arranged with at least one protrusion enabling said first fluid container to be assembled to said fluid transfer device using a turning motion in a first predetermined direction, and that said at least one protrusion is adapted to be disabled during said turning motion thus permitting said first connection part to be turned in any direction with respect to said second connection part.
