The invention relates to a downlight fixture, comprising: a support member coupled to a flange and having an upper region spaced from the flange to a lower region closer to the flange than the upper region. The support member comprises one or more side surfaces and a recess, a tab is moveably coupled to the support member such that at feast a part of said tab is moveable between a first position, where a part of the tab is protruding beyond the support member's side surface and a second position where the tab is positioned in the recess without any part extending beyond the support members side surface. A screw that extends substantially between the upper region of the support member and the lower region of the support member, said screw and said tab being threadedly connected such that rotation of the screw initially causes the at least part of said tab to move from its first position to its second position and further the tab to move towards or away from the flange. Said screw is in releasable engagement with said support member and that said releasable engagement is adapted such that the screw is maintained in the position where it extends substantially between the upper region of the support member and the lower region of the support member as long as turning of the screw causes the tab to move unobstructed towards the upper region of said support member and releasing the screw when the tab meets an obstruction.
