Date Jan. 12, 1989.Loss of the key to a lock equipped with a lock cylinder has the result that the respective lock can be opened only with a considerable loss of time and expenditure of funds. This problem is solved in that an extraction device is provided for lock cylinders in door locks or the like. This device is characterized by a supporting bridge (1) equipped with a passage bore (4) for a self-tapping screw (5) to be inserted into the lock cylinder to be extracted so as to act as tension rod and with two lifting screws (2) arranged in the end region of the supporting bridge (1) and oriented parallel to the passage bore (4). With this device it is possible, in particular, to prevent the door from being damaged when the lock cylinder is extracted.
