<p>A slider for a zip fastener with two tabs, includes a hollow body in which are housed two levers positioned on opposite sides of the teeth of the fastener, one of the two levers, provided with a pawl for insertion between the teeth to lock the slider, being operable by acting on either one of the tabs to overcome the resistance of an elastic element positioned within the hollow body which keeps the pawl inserted between the teeth. The elastic element includes an elastically flexible strip, having one end fixed to the lever provided with the pawl, the strip facing an internal wall of the hollow body in such a way that it is interposed between the body and this lever and its elastic resistance opposes a movement of the lever which causes the extraction of the pawl from the teeth.</p> |
