Abstract: 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.

Abstract: A self-locking band, to be used as a seal or a tag holder, has an integral elastomeric body which forms a flexible stem terminating at one end in a double hook and on the other end in a flat sleeve formed with two pairs of internal barbs of dovetail shape facing in opposite directions. The stem is attached midway to the sleeve, allowing its hook to be inserted into the sleeve from either end thereof for interengagement with the corresponding pair of barbs.
