The device includes a receiving member adapted to be disposed in a track having a channel which supports a plurality of attachment elements. The receiving member has securing means with a first and a second position, a biasing means biases the securing means in the first position. A loading/unloading member, with a channel, has engagement slots adapted to removably engage with the securing means. The loading/unloading member can be engaged, or disengaged, from the receiving member by a single operator movement. When engaged, attachment elements can be moved between the track channel and the loading/unloading member channel.
