The invention relates to a finger ring fastening as a holder for a suction/lighting tubing. The diameter of the ring is adjustable and can hence be matched to the diameter of the finger. The circumference of the tube fastening is also broken but is not adjustable. The tube acts in this case as a snap fastening for a suction/lighting tubing where such tubings are ductile. The tube fastening is fixed to the ring part by an axle, the tube being rotatable in the lateral direction. With the said invention, a "3rd. hand" is created for the operator. <IMAGE> |
