Coupling device

A medical tube for transferring a fluid to or from a patient, wherein the medical tube comprises:

• at least one coupling device comprising:
• a first housing extending along a principal axis, the first housing comprising a first opening at a back end portion thereof, a second opening at a front end portion thereof, and a tube portion extending from the first opening into the first housing;
• a second housing displaceably arranged within the first housing along the principal axis between a first position at the front end portion of the first housing and a second position at the back end portion of the first housing, the second housing comprising a first sealing element;
• and
• a third housing releasably connectable to the second housing and configured for displaceable arrangement within the first housing along the principal axis, the third housing comprising a channel through the third housing, and a second sealing element arranged to seal the channel,
• whereby, in the first position of the second housing, the third housing is insertable into the first housing via the second opening thereof, and insertable between the first housing and the first sealing element, such that the first and second sealing elements are configured to abut each other and sealingly separate the tube portion and the channel, and whereby, in the second position of the second housing, the third housing and the second housing are connected and the tube portion projects through the first and second sealing elements for connection with the channel such that a transfer of the fluid through the at least one coupling device is enabled.
