An attachment system for hand-held tools comprising: a housing with a proximal housing end portion , a distal housing end portion , and a perimeter wall defining an open central region within the housing, the perimeter wall having a first slot and a second slot spaced from the first slot , each with a predefined slot width and extending through the perimeter wall to the open central region , wherein the first slot and the second slot each has a proximal slot end and a distal slot end , the proximal slot end having a proximal slot end width that is greater than the predefined slot width; a rotating member disposed in the open central region and configured to rotate about a central longitudinal axis between a first position and a second position, the rotating member having a sloping surface and a catch surface where both extend transversely from the rotating member and wherein the sloping surface is aligned with one of the first slot and the second slot ; a clip member having a clip body with a housing-side surface and a clip protrusion having a neck portion and a head portion wherein the clip protrusion extends transversely away from the housing-side surface , the clip protrusion adapted to be slidably received in and retained by one of the first slot and the second slot wherein the clip protrusion engages the sloping surface of the rotating member to move the rotating member to either the first position or the second position and to either retain the clip protrusion within or to release the clip protrusion from the housing ; wherein the clip protrusion moving distally in the first slot a sufficient distance causes the rotating member to rotate in a first direction about the central longitudinal axis and causes the catch surface to rotate beneath the clip protrusion to retain the clip member in engagement with the housing . a housing with a proximal housing end portion , a distal housing end portion , and a perimeter wall defining an open central region within the housing, the perimeter wall having a first slot and a second slot spaced from the first slot , each with a predefined slot width and extending through the perimeter wall to the open central region , wherein the first slot and the second slot each has a proximal slot end and a distal slot end , the proximal slot end having a proximal slot end width that is greater than the predefined slot width; a rotating member disposed in the open central region and configured to rotate about a central longitudinal axis between a first position and a second position, the rotating member having a sloping surface and a catch surface where both extend transversely from the rotating member and wherein the sloping surface is aligned with one of the first slot and the second slot ; a clip member having a clip body with a housing-side surface and a clip protrusion having a neck portion and a head portion wherein the clip protrusion extends transversely away from the housing-side surface , the clip protrusion adapted to be slidably received in and retained by one of the first slot and the second slot wherein the clip protrusion engages the sloping surface of the rotating member to move the rotating member to either the first position or the second position and to either retain the clip protrusion within or to release the clip protrusion from the housing ; wherein the clip protrusion moving distally in the first slot a sufficient distance causes the rotating member to rotate in a first direction about the central longitudinal axis and causes the catch surface to rotate beneath the clip protrusion to retain the clip member in engagement with the housing . <EOS>
