WIRE CLAMP Russian patent published in 2017 - IPC F16L33/00 

FIELD: ventilation.

SUBSTANCE: wire clamp is a ring 1 made of wire stranded in an arc of a circle less than one turn. At the ends of the ring 1, ears 2 are made in the form of a loop bent one turn so that there is still a shank 3. Sections 4 are made in the shanks 3. Ears 2 interact with hooks 5, made in screeds 6. In the screeds 6, the guides 7 and 8 are also made. To tighten the ring 1 with the help of ties 6, there is a pin 9 having threads of different directions at the ends. The hairpin 9 is screwed into the corresponding holes made in the screeds 6. When tightening the couplers 6, the guides 7 and 8, interacting with the cuts 4 of the shanks 3, create a corresponding pressure in the joint between the lugs 2.

EFFECT: ensuring tightness.
