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. The coupling device further comprises a third housing (300) releasably connectable to the second housing and displaceably arranged within the first housing when connected to the second housing. In a first position of the second housing, the first and second channels constitute a passage which is sealed by the first and second sealing elements when the second housing and the third housing are connected. In a second position, the tube portion projects through the first and second sealing elements and into the sealed passage for enabling a transfer of fluid through the coupling device.
