Abstract
The invention comprises a door closer (), a slide rail () and an arm (). The arm is connected to the door closer () and to the slide rail (). The slide rail is provided with a hold open device () in order to keep a door open. The arm () comprises an outer arm (A,A) and an inner arm (B,B). The inner is situated partly inside the outer arm in a sliding manner. The arm () also comprises a spring arrangement () in order to hold the inner arm (B,B) in a normal position in the outer arm (A,A), and a release device (A,B).
