An improved restraining strap and method of using same is provided for securely attaching pressure vessels tanks to the supporting structure of a vehicle. Each strap has an extensible, elongated body which is lies over the tank and has first and second ends which are attached rigidly to the structure. A plurality of V-bends are spaced along the body between the first and second ends, each V-bend has an apex displaced out-of-line of the body so that when the tank is cycled between its contracted and expanded states, the body of the strap elastically shortens and lengthens while each V-bend flexes within the elastic range and providing a consistent vessel holding force. The holding force is sufficient to withstand acceleration and deceleration of the vehicle under normal operating conditions as well as under most impact conditions, whether the tank is fully expanded (pressurized) or fully contracted (depressurized).
