Abstract: A collar attached around a nozzle has a pivot from which an arm extends. In a contracted position, the arm extends close along the nozzle toward the discharge end thereof to facilitate insertion of the nozzle into an opening of a tank. While in the opening, the arm is turned far enough, by an extension outside the opening, through an acute angle to contact the inside edge of the opening and therefore to force the nozzle in an opposite direction against the inside edge. A latch connected to the arm maintains, until the latch is released, the arm in an expanded or wedging position for retaining the nozzle in the opening. Another embodiment uses three arms evenly spaced for wedging the nozzle in a centered position in an opening.
