The spring holder (10) has a pin, which extends through the rotary spring (11a,b). First and second flanges (12a,b) are fixed to the pin and against which the first and second spring arms support. The second spring arm has a part extending outside the second flange, which locates against a hatch (3). The spring holder is removable and rotatably connected around a geometrical axis concentric with the pin to a fixture (7) on a wall (1). The spring holder is rotatable from a starting position, in which the second spring arm supports against the second flange and its extending apart locates against the hatch. |
