Abstract
A nozzle holder has a deformable end portion adapted to be passed through a hole in a distribution plate of an up-flow filter, whereby this end portion lies below the lower side of the plate. A nozzle extending through the holder engages the deformable end portion internally to maintain it in expanded condition and thereby prevent it from being withdrawn upward through the hole, and clamping means coacting with the holder at the upper side of the plate serve to clamp the expanded end portion of the holder against the lower side of the plate. This arrangement enables the nozzle to be installed entirely from above the plate.
