A needle assembly for a tagger gun includes a needle carrier (43) slidably disposed within the tagger gun casing, a needle (45) removably mounted into a needle bore (49) in the carrier (43), and a needle lock (47) snap-mounted into a needle lock bore (51) in the needle carrier (43). The needle lock (47) includes a locking post (71) having a first end and a second end, and an enlarged head formed onto the second end. The locking post (71) is shaped to include a longitudinally-extending slot (77) which bifurcates the first end (73) into a pair of paralle fingers (79). a ratchet-shaped tooth (81) is formed onto each finger (79), each tooth (81) including a tapered surface (83) for guiding the needle lock (47) into the needle lock bore (51) and an engagement surface for retaining the needle lock (47) mounted in the needle carrier (43). |
