A feeder tube assembly for a feeder bowl of a glass melting furnace forehearth. The feeder tube assembly has an horizontally extending elongate support arm, and a feeder tube that is carried by the support arm at a location near an end of the support arm. The feeder tube is held in place by a clamping ring that engages a flange of the feeder tube at an end of the feeder tube. The clamping ring is releasably held in engagement with the flange of the feeder tube by a plurality of latch mechanisms that are circumferentially spaced apart. Each latch mechanism has a lever with a rounded cam surface and a handle that extends away from the cam surface and is pivotally attached to a support member. The support member, in turn is pivotally attached to a fixed member, and pivoting of the pivoted support member relative to the fixed member is effective to swing the lever out of interfering relationship with the clamping ring to facilitate removal of the clamping ring.
