Abstract: A device is fitted into a well of a one-piece wheel rim so as to prevent a tire fitted onto the rim from rolling off this rim. A process for manufacturing this device is disclosed as is a fitted assembly for a motor vehicle comprising the rim, the cover and the device. The device has a belt having two ends and a catching blocks for connecting the ends together, which is intended to clamp the belt of annular shape around the rim well, and this device is such that the belt includes a plurality of filling elements, spaced apart between the ends, which elements are designed to at least partly fill the well and are connected together via at least one flexible linking element intended to form an annular sector around the well.

Abstract: The present invention relates to a device designed to be fitted into a well of a one-piece wheel rim so as to prevent a tire cover fitted onto said rim from rolling off this rim, to a process for manufacturing this device and to a fitted assembly for a motor vehicle comprising said rim, said cover and said device. A device according to the invention comprises a belt having two ends and a connecting means for connecting said ends together, which means is intended to clamp said belt of annular shape around the rim well, and this device is such that said belt includes a plurality of filling elements, spaced apart between said ends, which elements are designed to at least partly fill said well and are connected together via at least one flexible linking element intended to form an annular sector around said well.
