Claims7
A connection clamping device arranged for connecting a flexible tube to a barbed end of a connection means, whereby the barbed end comprises a barb and the connection means during connection is arranged to protrude into an end of the flexible tube, characterized in that said connection clamping device comprises two halves which, during connection when the connection means protrudes into an end of the flexible tube, are arranged to be connected and locked to each other by a locking mechanism around the connection means and the flexible tube, such that the flexible tube is compressed against the connection means by a first rib provided on the inner circumference of the connection clamping device,
- wherein an inner diameter of the connection clamping device except from where the first 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 first rib is less than the outer diameter of the flexible tube,
- wherein the first rib is configured to create a space between the connection clamping device inner diameter and the outside diameter of the flexible tube,
- wherein a second rib is provided in the two halves, whereby the second rib is arranged to compress the flexible tube against a coned surface of the barbed end, above the barb when the connection clamping device is provided for clamping the tube to the connection means, and
- wherein a positioning rib is provided in the connection clamping device, whereby the positioning rib is arranged to be adjacent to a connection means rib on the connection means when the connection clamping device is provided for clamping the tube to the connection means for aligning the connection clamping device axially with the connection means.
A method for connecting a flexible tube to a barbed end of a connection means, said method comprising the steps of:
- providing the connection means protruding into an end of the flexible tube;
- providing a connection clamping device around the flexible tube and the connection means when the connection means protrudes into the tube, said connection clamping device comprises two halves comprising a first rib, a second rib, and a positioning rib, wherein the two halves are connected and locked to each other during this step;
- and
- squeezing the flexible tube against the connection means by a first rib provided on a part of an inner surface of the connection clamping device around a circumference of the flexible tube, wherein the first rib is configured to create a space between part of the inner surface of the connection clamping device and the outside diameter of the flexible tube, and the second rib is configured to squeeze above the barb on the barbed end, and whereby the positioning rib is arranged to be adjacent to a connection means rib on the connection means when the connection clamping device is provided for clamping the tube to the connection means for aligning the connection clamping device axially with the connection means.
