The device described by the patent concerns a locking collar for rainwater pipes, consisting of two strips 1 and 2, in the shape of a sector of a circle, of different lengths forming a circular structure when joined together. The strip 1 of shorter length is essentially rigid while the other 2 is flexible. The two strips have, corresponding with the two ends that fit together, a pair of radial lugs 4, 5 for the insertion of means for fixing them together 3, while corresponding with the other end of the rigid strip 1 there is a hook part 6, that can be hooked to one of the holes 7 in the other strip 2 (fig. 2). <IMAGE> |
