An adjustable locking strap includes a first loop, a second loop, and an adjustable strap extending therebetween. The second loop can be adjustable in size. The first loop can be fit about a first end of the elongate object, and the second loop can be positioned about a second end of the elongate object and adjusted for proper size. The strap extending between the loops can be adjusted between the loops so that when the first and second loops are positioned about the elongate object, the strap is sized to prevent either loop from being removed from the object. A lock is interconnected with the adjustable loop and strap for securing the size of the adjustable loop and strap. A tether portion can secure the locking strap to a fixed object. A stopper on the tether can be positioned within a car, and the window rolled up to retain the locking strap within a car. A storage bag can be interconnected with the strap for convenient storage thereof.
