<p>The key holder case encloses keys so that each is connected with rings or hooks which in turn, have a detachable attachment to holding devices forming one part of the case. The holder head is in the form of a pipe shaped body having a number of parallel circumferential slots offset in relation to each other which only partially exert pressure on the cylindrical body wall. They lead at one end to a widened section crossed by the holding head of the hooks. The pipe-shaped body may be turned by hand around its axis so that in a first position the widened sections are at least partially covered by a cover device, whereas in a second position the widened sections are lying free. The second position is held against spring press.</p> |
