a tubing attachment component having a proximal end, a distal end, and an external surface, the tubing attachment component comprising a proximal end portion configured to attach to the tube, a distal end portion configured to attach to the handpiece, a throughbore extending from the distal end to the proximal end, and a circumferential groove on the external surface between the proximal end portion and the distal end portion;

wherein the frame and the at least one locking protrusion are configured to fit in the circumferential groove and be rotatable in the circumferential groove about the tubing attachment component when an external force is applied and to frictionally lock the tubing attachment component in a desired rotational position in the absence of such external force;

wherein the proximal end portion includes a conical body transitioning into a radially outwardly extending barb for securing the tube, and the distal end portion includes a fitting for engaging a corresponding fitting on the handpiece; and

wherein the tubing attachment component further comprises a flange between the conical body and the fitting, and the flange forms a rail of the circumferential groove.

2. The tubing attachment system of claim 1 , wherein the tubing clip includes one or more channels defined by the one or more tube retaining arms.

3. The tubing attachment system of claim 1 , wherein the at least one protrusion includes a contact surface facing inwardly that extends from a proximal end to a distal free end of the at least one locking protrusion.

4. The tubing attachment system of claim 2 , wherein the one or more channels and the frame opening are parallel to each other.

5. The tubing attachment system of claim 1 , wherein the tubing clip includes a plurality of the at least one locking protrusion spaced circumferentially about the frame opening.

6. The tubing attachment system of claim 1 , in combination with an ultrasonic surgical apparatus having a handpiece and a tube connected to the proximal end portion of the tubing attachment component.

7. A tubing attachment system comprising:

a tubing clip having a frame having an internal frame surface, an external frame surface, and a frame opening defining a longitudinal axis, the frame including at least one locking protrusion extending inward from the internal frame surface, and wherein the at least one locking protrusion defines the frame opening, and

wherein the tubing clip includes one or more tube retaining arms extending outwardly from the frame;

wherein the at least one locking protrusion includes a first contact surface facing inwardly that extends from a proximal end to a distal free end of the at least one locking protrusion; and

wherein the at least one locking protrusion includes a second contact surface at the distal free end facing axially away from the frame in a direction along the longitudinal axis.

8. The tubing attachment system of claim 7 , wherein the tubing clip has a plurality of the at least one locking protrusion disposed on the internal frame surface of the frame.

9. The tubing attachment system of claim 7 , wherein the one or more tube retaining arms form a channel configured to hold another tube.

10. The tubing attachment system of claim 7 , further comprising a tubing attachment component having a proximal end, a distal end, and an external surface, the tubing attachment component comprising a proximal end portion configured to attach to the tube, a distal end portion configured to attach to the handpiece, a throughbore extending from the distal end to the proximal end, and a circumferential groove on the external surface between the proximal end portion and the distal end portion;

wherein the frame and the at least one locking protrusion are configured to fit in the circumferential groove and be rotatable in the circumferential groove about the tubing attachment component when an external force is applied and to frictionally lock the tubing attachment component in a desired rotational position in the absence of such external force;

wherein the proximal end portion includes a conical body transitioning into a radially outwardly extending barb for securing the tube, and the distal end portion includes a fitting for engaging a corresponding fitting on the handpiece; and

wherein the tubing attachment component further comprises a flange between the conical body and the fitting, and the flange forms a rail of the circumferential groove.

11. The tubing attachment system of claim 7 , in combination with a medical apparatus, wherein the medical apparatus is an ultrasonic surgical apparatus.

12. A medical apparatus comprising:

a handpiece and a tube, wherein the tube is connected to the handpiece through a swivel joint which allows the tube to rotate circumferentially with respect to the handpiece without axial displacement of the tube; and

wherein the swivel joint further comprises:

a tubing attachment component having a longitudinal throughbore and a circumferential groove on an external frame surface, wherein a bottom wall of the circumferential groove increases in depth towards the longitudinal throughbore; and

a tubing clip having a frame with a frame opening defining a longitudinal axis and at least one locking protrusion having a first contact surface facing inwardly and narrowing the frame opening along the longitudinal axis, wherein the first contact surface of the at least one locking protrusion extends from a proximal end to a distal free end of the at least one locking protrusion, wherein the first contact surface of the at least one locking protrusion contours to and frictionally engages the bottom wall of the circumferential groove of the tubing attachment component, and wherein the at least one locking protrusion includes a second contact surface at the distal free end facing axially away from the frame in a direction along the longitudinal axis;

wherein the frame can be snapped into the circumferential groove of the tubing attachment component and rotate about the tubing attachment component; and

wherein the at least one locking protrusion allows the tubing clip and tubing attachment component to be fixed at a desired relative position.

13. The medical apparatus of claim 12 , wherein the tubing clip includes a plurality of the at least one locking protrusion extending radially inward from an internal frame surface of the frame.

14. The medical apparatus of claim 12 , wherein the tubing attachment component further comprises a flange extending from the external frame surface of the tubing attachment component and defining a longitudinal extent of the circumferential groove.
