In a method for securing an elastic, circumferential seal (1) on a tubular element (2), a base portion (4) of the seal (1) is applied against the tubular element (2), whereupon a clamping strap (7) is tightened on the base portion (4) to clamp this portion against the tubular element (2) with sealing lips (5) projecting therefrom. The clamping strap (7) and thus the seal (1) are anchored by a pointed, piercing rivet (12, 13) being driven through the clamping strap (7), the base portion (4) and the wall of the tubular element (2), and upset against a fixed abutment (9). During the upsetting operation, the rivet shank (13) forms a bulge (17) whose transverse dimensions exceed the transverse dimension of the hole which is pierced through the wall of the tubular element (2) by the rivet (12, 13), whereby the rivet and the seal are prevented from being pulled off the tubular element. A device for carrying out the method comprises, in addition to the above-mentioned components, a stamping means and, cooperating therewith, an abutment means (9-11). <IMAGE> |
