Connection clamping device

1. A connection clamping device for bioprocess disposables, arranged to secure a flexible tube to a barbed end of a tube connector, the barbed end comprising a barb and the tube connector during connection being arranged to protrude into an end of the flexible tube,

wherein said connection clamping device comprises a first section and a second section which, during connection when the tube connector protrudes into an end of the flexible tube, are arranged to be connected and locked to each other in a clamped position by a locking mechanism around the tube connector and the flexible tube, such that the flexible tube is compressed against the tube connector by a rib provided on the inner circumference of the connection clamping device,

wherein said connection clamping device further comprises one or more anti-rotation teeth protruding inward from an inner surface, wherein said one or more anti-rotation teeth has a tooth height less than a height of said rib, and

wherein the externally exposed surfaces of said connection clamping device in a clamped position are rounded and do not define sharp corners or sharp edges to prevent damage to said bioprocess disposables.

2. The connection clamping device according to claim 1 , wherein said connection clamping device comprises:

a first part of the rib provided in the first section and a second part of the rib provided in the second section, which rib parts together form the rib over the inner circumference of the tube formed part when the two sections are locked together,

wherein the first section and the second section of the connection clamping device are arranged to be positioned around and locked around the flexible tube and the tube connector when the tube connector protrudes into the tube and the first rib is arranged to squeeze the flexible tube against the tube connector below the barb provided on the tube connector.

3. The connection clamping device according to claim 1 , wherein an inner diameter of the connection clamping device except from where the rib is provided is larger than an outer diameter of the flexible tube and an inner diameter of the tube formed part at the position for the rib is less than the outer diameter of the flexible tube.

4. The connection clamping device according to claim 1 , wherein the two sections are connected to each other on one side by a living hinge.

5. The connection clamping device according to claim 1 , wherein the locking mechanism is arranged on a first connection surface of each of the two sections and the locking mechanism is one or more protruding latches on one of the sections and recesses on the other of the two sections.

6. The connection clamping device according to claim 1 , wherein the locking mechanism is arranged on both a first and a second connection surface of each of the two sections and the locking mechanism is one or more protruding latches on one of the sections and recesses on the other of the two sections.

7. The connection clamping device according to claim 1 , wherein an indicator recess is provided in a side wall of one or both of the two sections.

8. The connection clamping device according to claim 7 , wherein said indicator recess extends from an end wall of one or both of the two sections.

9. The connection clamping device according to claim 8 , comprising indicator recesses extending from both a first and a second end wall of one or both of the two sections.

10. The connection clamping device according to claim 1 , which is symmetrical around a transverse plane.

11. The connection clamping device according to claim 1 , wherein the rib is a first rib, wherein a second rib is provided in the two sections, and

wherein the second rib is arranged to compress the flexible tube against a coned surface of the barb when the connection clamping device is provided for clamping the tube to the tube connector.

12. The connection clamping device according to claim 1 , characterized in that it comprises a positioning rib arranged to counteract with a tube connector rib for aligning the connection clamping device axially with the tube connector.

13. The connection clamping device according to claim 1 , further comprising one or more plier recesses in a side wall of one or both of the two sections.

14. The connection clamping device according to claim 1 , wherein each of the two sections has a side wall having a recessed waist portion.

15. The connection clamping device according to claim 1 , which is arranged to secure a flexible tube of particular inner and outer diameters to a tube connector of corresponding outer diameter and which is optically coded to indicate the compatibility with said tube and tube connector.

16. The connection clamping device according to claim 1 , further comprising a first and a second external rib protruding from an outer surface.

17. The connection clamping device according to claim 1 , wherein the anti-rotation teeth comprise an edge at a distal end of the teeth arranged to penetrate into the flexible tube.

18. The connection clamping device according to claim 1 , wherein said rib of the connection clamping device is the only rib provided on the inner circumference of the connection clamping device.
