ABSTRACT:
A flat strip is bent into a discontinuous loop with an end of one limb slanted to contact the inner side of the other limb so that two semi-circles are separated by one continuous limb length and one discontinuous limb length. The continuous length is slotted for at least one-half of its long dimension, with a wider aperture at the upper end. Key hooks, preferably for individual keys, that have a large head and a large closed circle at opposite ends of a small shank fit into the slot, retained by the end of the discontinuous limb that slants across the space between limbs. The loop provides passage for a belt or other support above a thruster that affords a way of separating the limbs to move key hooks in and out of the loop past the slanted limb end or lock.
More than one key hook may be used and one way of separating hooks includes a small disc or drum rotatably seated at the bottom of the slot in the continuous limb.
