The second fixing member is movable between a first position in which it is disengaged from the first fixing member and a second position in which the second fixing member engages the first fixing member to thereby arrest the door in the open position thereof. The second fixing member does not have any direct contact with the elongated sleeve during movement thereof between the first and second positions.
