<p>The device for locking a roller shutter incorporates clamp units on hinged mountings, activated by an adjusting mechanism. The guide-rail and clamp unit are connected with the shutter guideway (2') with hinge components (8a, 8b) which can be hung in place, so as to be able to swivel. The hinge components may be provided by protrusions formed on the clamp units and shutter guideway, and they may be insertable into one another. The fixed hinge part can be mounted on the stem of a U-shaped guideway (2). There can be a return spring in the shape of a tongue formed onto the plug head.</p> |
