A stretchable tie-down device includes an elongated resilient stretchable tube, which is thin walled and pliable to collapse and flatten readily when pressed against a surface for gripping it frictionally and snugly. At least one hook member is fixed to the tube at one end thereof by means of a plug, which is disposed within the tube and for fixing it to the tube. The tube has a non-circular cross-sectional configuration throughout its length to provide a substantial surface area for facilitating the gripping of surfaces with the cord device. The hook member includes a flat metal hook having an outer coating of thermoplastic material thereon.
