A tool for use in loading a transcatheter valve prosthesis within a delivery catheter includes a body portion, a pivotable element and a biasing element. The body portion includes a central passageway extending form a proximal end to a distal end of the body portion. The central passageway is configured to receive a distal portion of a delivery catheter therethrough. The pivotable element is attached to the body portion and is configured to secure a tether during loading of a transcatheter valve prosthesis within the delivery catheter. The biasing element compresses the pivotable element against the body portion such that the pivotable element holds a second end against the delivery catheter and secures the tether thereto. The pivotable element may be two or more pivotable elements.
