There is disclosed an apparatus for attaching tags to merchandise using fasteners. The fasteners are arranged in a one-piece fastener assembly. Each fastener includes a bar section and a button section joined by a filament section. The apparatus includes a body and a needle connected to the body. A fastener advancing means is used to advance one fastener at a time into dispensing relationship with the needle. The fastener advancing means includes a toothed wheel. A one-piece pawl includes a U-shaped portion having a pair of flexible resilient arms. One of the arms has a tooth cooperable with the toothed wheel and the other arm is cooperable with an annular bearing surface which is disposed adjacent the wheel. The pawl includes a pair of integrally formed flexible resilient members or arms providing abutment faces. A pair of drive faces is connected to a gear segment which is driven by a manually operable actuator. One drive face is cooperable with one abutment face to drive the pawl from a first position to a second position and the other drive face is cooperable with the other abutment face to drive the pawl from the second position to the first position to cause the toothed wheel to cause advance of the fastener assembly. As the pawl is driven from the first position to the second position, a push rod is driven to drive a bar section of a fastener through the needle.
