An adjustable fixing device ( 1 ) for a roof drain ( 2 ) adapted to be mounted in a roof construction consisting of a supporting roof ( 3 ) and a water sealing membrane layer ( 4 ), possibly interleaved with isolation ( 5 ). A first portion of the device ( 1 ) is fastened to the roof drain ( 2 ), or to a part rigidly fastened thereto, and a second portion is fastened to the supporting roof ( 3 ). The device includes a ring-like member, fitting around a pipe ( 9 ) integral with the drain ( 2 ). At least one enclosing member enclose, at least partially, the ring-like member and has a surface adapted to mutually cooperate with at least a part of the ring-like member. At least one tightening member is adapted to apply a pressure on the at least one member, whereby the surface of the at least one member presses on the corresponding surface of the ring-like member, which thereby clamps the pipe ( 9 ).
