An elongated unitary loop element of resilient material and made of an essentially flat strap is bent into a flattened loop with two overlapping end portions. The overlapping end portions overlap by a distance which is at least in the order of about of the spacing of the overlapping end portion from the opposite flattened loop side, the outer one of the overlapping end portions being formed with an angled tip extending away from the loop, the overlapping end portions being resiliently biased against each other by the material but permitting resilient deflection upon pressure against the outer one of the overlapping end portions to form an access space for removal of the key, or tool upon deflection pressure against the outer one of the overlapping end portions which will form a fulcrum over which the inner one of the end portion can tip, the overlapping end portions when undeflected, being in tight engagement, which may include an interlocking connection, to prevent removal of the key or tool and to eliminate any possible access space between said overlapping end portions.
