Have you ever struggled with the cable of your vacuum cleaner rewinding by itself? That's exactly what happened to me. Rather than buying a new vacuum cleaner, I have used a clip to hold the cable in place. But the clip has many downsides, and most of the time it doesn't work after a while. So I came up with this specific design to hold the cable in place, reusing the spring from the clip. You can customize this to your vacuum cleaner's dimensions.
