In a push-button lock for safety belts there is provided a base plate and a cover plate which is mounted on the base plate. For this mounting the base plate forms two upwardly bent marginal flanges at two opposite side margins and the cover plate forms an opening to be threaded on one of the flanges by such opening, as well as projections for engagement with said one flange from the outer side thereof and with the other marginal flange from the inner side thereof by lateral displacement of the cover plate. There is provided on the cover plate a manually operable blocking member which may be set against the inner side of said one flange for retaining the cover plate in a position in which it is connected with the base plate by the engagement between the projections and the flanges. |
