A key holder comprising in combination a housing and a ring member, the housing having a resilient tongue which may be depressed so as to provide an opening through which the ring member may be inserted. The ring member is provided with a slit which permits keys to be attached and detached, said slit being inaccessible when the ring member is assembled to the housing, whereupon keys can be attached to or detached from the ring member only when the latter has been separated from the housing. |
