A device comprising a securing means and a latching means for latching a door in a pre-determined position of rotation relative to a frame associated with said door when rotating the door in one direction. Means is securely attached to the door and arranged to coact with the door at its upper horizontal edge surface. The latching means extends from the securing means in the form of a horizontally or substantially horizontally extending portion. The securing means and the latching means are pivotally arranged relative to each other and exhibit locking means, which are adapted to co-act with each other so that the latching means is able to adopt one of two position of rotation relative to the securing means. A first position of rotation in which closing of the door 1 is prevented and a second position of rotation in which the door is free to close. The securing means and the latching means are formed integrally of a plastics material. The rotation of the latching means is effected via a thin portion formed between the latching means and the securing means.
