Abstract: The "alarm fastening for roller blinds" is intended to prevent roller blinds from being opened from outside and to emit an acoustic alarm signal in response to an attempt at opening. The alarm fastening is also to perform this function on doors which have at least one door latch, in that the upper strap end is clamped in the door at the top and the strap loop of the lower strap end is suspended on the door latch. The door latch can consequently no longer be pressed downwards. An alarm sound is triggered at the slightest attempt. The use of the "alarm fastening for roller blinds" achieves an effective deterrent effect on intruders and residential break-ins can be reduced at least to a great extent. The safety of people and their property is increased. <IMAGE>
