Toilet hinge arrangement comprising a toilet cover assembly including a toilet seat and a toilet seat cover cover for fastening to a toilet bowl, where by means of the toilet hinge arrangement, the toilet seat and toilet seat cover may pivot around a central axis, where said toilet hinge arrangement comprises: - A rotational damper, said damper having a pivot axis parallel to the central axis, where the damper has a housing enclosing the dampening mechanism, such that a damper shaft extends outside the housing in one end, and engagement means, for engaging fastening means on the toilet bowl, are provided in the opposite end of the damper; - A catch ring, adapted to be mounted on and held by the part of the damper shaft extending from the damper housing, where the catch ring has a central body, where one or more spring action catches resiliently extend from said central body, where the spring action catches may be urged towards the central body such that the one or more spring action catches lie within an outer perimeter of said central body; - An adapter ring adapted to be mounted on and held by the part of the damper shaft extending from the damper housing, and abutting the catch ring, and where opposite to the side abutting the catch ring a resilient member is provided, said resilient member being biased away from the adapter ring in a direction parallel to the central axis, and where said adapter ring is provided with at least one engagement surface; and where the toilet seat and the toilet seat cover respectively each is provided with two ear lugs (11, 13), one adjacent to each side of the toilet seat and toilet seat cover respectively, where the ear lugs of the toilet seat are arranged either inside or outside the ear lugs of the toilet seat cover, where the innermost ear lugs are provided with through-going apertures and where the outermost ear lugs are provided with cavities, said cavities having a bottom wall, where said through-going apertures and cavities are arranged coaxially with and covering part of the damper, catch ring and adapter ring, and where the end of the damper with the engagement means will not be covered by the ear lugs (11, 13); where on one side of the toilet cover assembly one or more of the spring action catches will be inserted into one or more catch cavities provided on the inside of the through-going aperture provided in the inner-most ear lugs, thereby releasably fixing the ear lug (11, 13) to the shaft of the damper, and in the opposite side the engagement surface of the adapter ring is engaged with an inner side of the cavity of the outermost ear lug; and the resilient member on the adapter ring being in resilient engagement with the bottom wall of at least one of the outermost ear lugs. - A rotational damper, said damper having a pivot axis parallel to the central axis, where the damper has a housing enclosing the dampening mechanism, such that a damper shaft extends outside the housing in one end, and engagement means, for engaging fastening means on the toilet bowl, are provided in the opposite end of the damper; - A catch ring, adapted to be mounted on and held by the part of the damper shaft extending from the damper housing, where the catch ring has a central body, where one or more spring action catches resiliently extend from said central body, where the spring action catches may be urged towards the central body such that the one or more spring action catches lie within an outer perimeter of said central body; - An adapter ring adapted to be mounted on and held by the part of the damper shaft extending from the damper housing, and abutting the catch ring, and where opposite to the side abutting the catch ring a resilient member is provided, said resilient member being biased away from the adapter ring in a direction parallel to the central axis, and where said adapter ring is provided with at least one engagement surface;
