First of all, sorry for the inconvenience, but I don't know where to look anymore! I'm looking for the name of a component that is often found in workshops and industrial production departments.

Do you remember the bridge cranes? Those that are used inside the workshops, there is like a guide that accompanies the cable with slots and allows the cable to fully extend. When the overhead crane goes back, this cable also pulls back by itself because it remains under tension.

I have also seen something similar for compressed air hoses connected to overhead brackets to be able to move freely in the workshop. These also used a similar system.

If you understand what I'm talking about..... does it have a name?

Update: just find a picture:
