A slider rest is formed on the top of a hollow, generally upright support structure or frame for holding a slider thereon in upside-down disposition with its pull tab telescopically received in a slit extending downwardly from the slider rest. Accommodated within the support structure is a pivotable locking lever having an offset detent at its top end which is movable into and out of engagement with an aperture in the slider pull tab received in the slit. Normally, the locking lever is held in its inoperative position by a retractable stop extending across the slit. Upon insertion of the slider pull tab into the slit, the retractable stop is thereby pivoted downwardly to permit the locking lever to be spring-actuated to its operative position where the detent engages the pull tab aperture and thus locks the slider on the slider rest. |
