Abstract
A coupling device (100) for transferring a fluid is provided. The coupling device comprises a first housing (110), a tube portion (140) projecting into the first housing, and a second housing (200) displaceably arranged within the first housing. A third housing (300) is releasably connectable to the second housing and displaceably arranged within the first housing when connected to the second housing. Control element(s) are configured to conditionally seal first and/or second sealing elements when the second housing and the third housing are connected. In a first position of the second housing, the tube portion and the channel are sealingly separated by the first and second sealing elements when the second housing and the third housing are connected. In a second position of the second housing, the tube portion projects through the first and second sealing elements for enabling a transfer of fluid through the coupling device.
