Abstract
A locking device for a covering comprised of a frame and a cover includes arms, which are inserted in depressions or bores formed in the frame and/or cover, whereby they undergo elastic deformation and consequently form a frictional engagement with the cover. The free end each of the arms project beyond an inner flange of the frame and form there a positive connection between the arms and the inner flange. This results in a simple, but effective connection between the cover and the frame, without requiring machining of the arms or depressions.
