The present invention is to provide a device configured for hanging, supporting and gripping, which includes a supporting element and a cover. The supporting element is a strip-like plate made of a flexible material and provided with at least two fasteners on one side proximate to the ends thereof and each including a stem and a fastener cap, wherein the stem is connected to the plate at one end and is connected to the fastener cap at the other end. The cover is formed with an assembly hole and a track groove in communication with the assembly hole, wherein the assembly hole is sized and shaped to allow passage of each fastener cap, and the track groove is not sized and shaped to allow passage of the fastener caps, thereby the supporting element can be fastened to the cover through the fasteners for hanging, supporting and gripping the cover accordingly.
