A spring, also housed internally of the locking lever, resiliently but releasably retains the Allen key until purposefully withdrawn by a workman. The key is returned to its confinement after the workman has finished using it for the purposes intended. The key is retained in an inconspicuous manner but nevertheless visible to the workman and readily extracted for use when desired.
