A gun for attaching tags of bar-lock type to a fabric has a body forming a barrel for the guidance of a plunger in line with a longitudinally slotted needle which is removably inserted into the front end of that body. A trigger articulated to the body is connected with the rear end of the plunger via a spring-loaded articulated linkage guided in an arcuate channel; the plunger has a head laterally inserted into a seat on an adjoining member of that linkage and can be laterally extracted from the barrel, e.g. for replacement upon an exchange of needles, after removal of a side cover and a grooved guide block adjacent thereto.
