The doors (1, 2) are of the type which slide in grooves (5, 6) in E-profiles (3) above and below. The catch (7) has a central plate (8) and wings (11, 12) which hinge away from the door. The catch (7) is fixed to the rear of one door (1). Both doors are allowed to open a short distance, before the edge (14) of the other door reaches the catch (7). The catch can be released by reaching inside and pressing the wings back against the door.
