One ear clip with inner ring
The fact that these clamps are used on very small-bore hoses means that the material of the tube or hose can sometimes be very flexible, making it more difficult to ensure a leaktight assembly due to the possible deformation of the hose. In these cases, the inner-ring is key in helping to guarantee leaktightness as well as protecting the hose from being pinched during assembly.
