Abstract: An apparatus for attaching equipment includes a base and one of a toolbox or tool accessory. The base has a primary engagement surface with a plurality of outwardly projecting male members each comprising a shaft with an enlarged head at a remote end. The toolbox or tool accessory has a secondary engagement surface with a plurality of inwardly recessed female receivers configured to receive the male members in mating relationship. A locking assembly is positioned within the toolbox or tool accessory. The locking assembly includes a movable catch that is movable between a locking position and a release position. In the locking position, the catch engages the enlarged head of each of the male members to prevent the male members from being withdrawn from the female receivers. In the release position, the catch is spaced from the enlarged heads of each of the male members.
