The invention relates to a device for connection of a cannula made from a flexible material to a tube. The aim of the invention is to provide a device for the connection of a cannula made from a flexible material to tubes, with which uncomplicated, rapid, secure and reproducible conditions for connectio n and disconnection are obtained, in particular under the conditions of an operative intervention for the connection of a heart-supporting or heart- replacement blood pump. Said aim is achieved by means of a device for the connection of a cannula made from a flexible material to a tube, whereby a tube spigot (4), fixed to the tube (5), is inserted in the cannula (7), characterised in that a claw ring (1), arranged on a cannula end (71), which may be displaced as far as a stop (2, 62), may be connected to and rotated with a locking ring (3), by means of axial displacement and clipping to the locking ring (3). Said connection may be undone again by means of rotating t he claw ring (1) and axially withdrawing the claw ring (1) and the cannula (7). |
