A subassembly for connecting a hose to a vacuum assembly , the subassembly comprising: a tubular body ; at least one locator projection extending from the tubular body , the at least one locator projection configured to be selectively slidable along at least one locator track of the vacuum assembly between a first end and a second end of the at least one locator track , wherein, when the at least one projection is positioned at the second end of the at least one locator track , the tubular body is rotatable, about an axis extending through the at least one locator projection and perpendicular to a vertical axis of the vacuum assembly , from a first position to a second position; and a second retention means disposed at the proximal end of the tubular body , the second retention means configured to be separated from a first retention means of the vacuum assembly when the tubular body is in the first position, the second retention means configured to releasably couple with the first retention means when the tubular body is in the second position, wherein, when the tubular body is in the second position and an axial load is applied to the tubular body in a direction extending from the proximal end toward a distal end of the tubular body , the at least one locator projection is positioned at the second end of the at least one locator track such that a load vector associated with the axial load does not extend through the axis of rotation of the tubular body and passes through the tubular body below the axis of rotation, such that the axial load does not cause the tubular body to move from the second position to the first position. a tubular body ; at least one locator projection extending from the tubular body , the at least one locator projection configured to be selectively slidable along at least one locator track of the vacuum assembly between a first end and a second end of the at least one locator track , wherein, when the at least one projection is positioned at the second end of the at least one locator track , the tubular body is rotatable, about an axis extending through the at least one locator projection and perpendicular to a vertical axis of the vacuum assembly , from a first position to a second position; and a second retention means disposed at the proximal end of the tubular body , the second retention means configured to be separated from a first retention means of the vacuum assembly when the tubular body is in the first position, the second retention means configured to releasably couple with the first retention means when the tubular body is in the second position, wherein, when the tubular body is in the second position and an axial load is applied to the tubular body in a direction extending from the proximal end toward a distal end of the tubular body , the at least one locator projection is positioned at the second end of the at least one locator track such that a load vector associated with the axial load does not extend through the axis of rotation of the tubular body and passes through the tubular body below the axis of rotation, such that the axial load does not cause the tubular body to move from the second position to the first position. <EOS>
