Abstract

The needle assembly is removably mounted in an attacher for dispensing tag fasteners of the type having a T-bar connected to a thin flexible filament. The base and shank of the needle include a channel along which the T-bar is moved by the push rod of the attacher and a slit through which the filament extends. A recess, preferably in the form of a slot, is provided in the wall of the shank, extending along the channel, at a circumferential position substantially perpendicular to the plane intersecting the shank and passing through the slit. The slot provides clearance for the T-bar to release from the push rod if the previously severed connecting element has become deformed by being wedged between the push rod and the channel wall.
