The present invention relates to a device at a water seal (1) for floor drains (2), said water seal (1) comprising a tubular member (3) and a cup-shaped member (4) which are located in centered positions relative to each other. The cup-shaped member (4) includes a centrally located coupling member (7) having at least one resilient tongue (13 and/or 14) which is provided for insertion into a centrally located, tubular coupling member (6) of the tubular member (3) and to thereby spring in a radial direction. The tongue (13 and/or 14) is provided to spring back such that the coupling members (6, 7) of the tubular member (3) and the cup-shaped member (4) in cooperation with each other connects said tubular and cup-shaped members (3, 4) to each other. <IMAGE> |
