Abstract

The invention relates to a device for non-destructive de-assembly of a threaded sleeve (7). The device has a threaded pin (1) having a first thread (2) which is formed in regions and by means of which the threaded pin (1) is partially screwed into a threaded sleeve (9), and a second thread (3) which is formed in regions and which is designed to run in opposite directions relative to the first thread (2). Furthermore, a counter sleeve (4) which has an internal thread and which is designed for screwing onto the second thread (3), is provided, wherein the counter sleeve (4) has a sleeve shaft (5) which, when screwing onto the second thread (3) on the end face counter to the an end face of the threaded sleeve (7) to be removed can be locked in such a way that the threaded sleeve (7) to be de-assembled can be freely rotated in the counter direction by rotating the lock sleeve (4).
