Abstract: A novel device that can be placed on a car gas cap to connect the cap to the car so that one cannot lose the cap due to forgetfulness or such. The device consists of an elastic body which can be stretched over the cap to allow for added friction grip to enable someone to remove or tighten the cap, and a connector strap assembly consisting of a flexible strap with a means of attachment to the car body. A suction cup is placed on the opposite side of the elastic body from the opening for the cap. This allows the user to attach the cap back out of his way while filling his gas inlet by merely pulling the cap back with the elastic body covering it and sticking out of his way conveniently and easily. Various sizes and shapes of car gas caps can be allowed for by the elastic nature of the device, however to give the best fit it is contemplated that several sizes will be available.
