An attachment system for hand-held tools comprising: a housing (12, 12') 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 (300, 400) 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 (300, 400) having a sloping surface (322, 324, 410a, 412a) and a catch surface (313, 410b, 412b) where both extend transversely from the rotating member (300, 400) and wherein the sloping surface (322, 324, 410a, 412a) is aligned with one of the first slot and the second slot; a clip member (100, 200) having a clip body with a housing-side surface and a clip protrusion (122, 222) having a neck portion (124, 224) and a head portion wherein the clip protrusion (122, 222) extends transversely away from the housing-side surface, the clip protrusion (122, 222) adapted to be slidably received in and retained by one of the first slot and the second slot wherein the clip protrusion (122, 222) engages the sloping surface (322, 324, 410a, 412a) of the rotating member (300, 400) to move the rotating member (300, 400) to either the first position or the second position and to either retain the clip protrusion within or to release the clip protrusion (122, 222) from the housing (12, 12'); wherein the clip protrusion (122, 222) moving distally in the first slot a sufficient distance causes the rotating member (300, 400) to rotate in a first direction about the central longitudinal axis and causes the catch surface (313, 410b, 412b) to rotate beneath the clip protrusion (122, 222) to retain the clip member (100, 200) in engagement with the housing (12, 12'). a housing (12, 12') 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 (300, 400) 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 (300, 400) having a sloping surface (322, 324, 410a, 412a) and a catch surface (313, 410b, 412b) where both extend transversely from the rotating member (300, 400) and wherein the sloping surface (322, 324, 410a, 412a) is aligned with one of the first slot and the second slot; a clip member (100, 200) having a clip body with a housing-side surface and a clip protrusion (122, 222) having a neck portion (124, 224) and a head portion wherein the clip protrusion (122, 222) extends transversely away from the housing-side surface, the clip protrusion (122, 222) adapted to be slidably received in and retained by one of the first slot and the second slot wherein the clip protrusion (122, 222) engages the sloping surface (322, 324, 410a, 412a) of the rotating member (300, 400) to move the rotating member (300, 400) to either the first position or the second position and to either retain the clip protrusion within or to release the clip protrusion (122, 222) from the housing (12, 12'); wherein the clip protrusion (122, 222) moving distally in the first slot a sufficient distance causes the rotating member (300, 400) to rotate in a first direction about the central longitudinal axis and causes the catch surface (313, 410b, 412b) to rotate beneath the clip protrusion (122, 222) to retain the clip member (100, 200) in engagement with the housing (12, 12').
