⬢Insert the metal end of the tube into the P-clamp.
If it is difficult to insert the tube into the P-clamp, loosen the nut a little. But be careful not to drop the P-clamp!
⬢Make sure the nut is accessible from the front.
⬢From the other side of the tube, slide the second P-clamp on the metal part of the tube. Mind the correct position of the P-clamp.
⬢Insert the nut into the P-clamp and attach it to the M3x12 screw on the left. Slightly tighten the screw using the Allen key from the top with your other hand - a few turns are enough for now. We will completely tighten it later.
