Abstract
In an example, a retainer may include a transition arm having a lift tab. The retainer may further include a pinch arm pivotably or movably engaged with the transition arm. The pinch arm may be movable between an engaged position and a stowed position, and may have a pinching member disposed on a pinching end of the pinch arm. Further, the transition arm may move the pinch arm form the engaged position to the stowed position upon the lift tab being moved about a retainer pivot point.
