A writing instrument is releasably attached to a tether. The writing instrument has a hollow body. A locking cap assembly is configured to be coupled to a tether. The locking cap assembly is further configured to detach from the hollow body of the writing instrument when a force is applied to the tether. The locking cap assembly is inserted into an end of the hollow body of the writing instrument. The locking cap assembly comprises a compressive locking cap. The compressive locking cap comprises a compression fastener, a cap, and a nut. The compression fastener and cap have a hole and one end of the tether passes completely through the compressive locking cap through the hole. The nut is coupled to the end of the tether that passed completely through the compressive locking cap.
