The utility model provides a sealing device that plumbing fixture is including having upside (23), downside (24), connect the part of packing into (2) of side surface (25) and at least one angle (26) of upside (23) and downside (24) and take part (16) including the seal membrane that has at least one sealed angle (1) and at least one. Sealed angle (1) inclines to extend and in base part spare (3), folding component (6) of two at least folding arris (5) that angular position (4) located to intersect and at least two lateral part parts (7, 8) connected each other via folding component (6) including having angularity ground each other, the lateral part part is connected via folding arris (5) and base part spare (3). Every take part (16) connect respectively one of lateral part part (7, 8) with base part spare (3) on to have equally in folding position folding arris (17), folding prism becomes the extension of folding arris (5) between lateral part part (7, 8) and base part spare (3). Sealing device is via base part spare (3) of sealed angle (1) and via taking parts (16) watertight feud to fix on downside (23) of the parts of packing into (2) in the mill.
