Drop pin for stop motion (1) comprising a body (2) with a yarn lead-through opening (3) provided to rest on a thread, extending through this opening (3), by means of a supporting edge (4), forming a concavely curved bordering of this opening (3) and which, in cross-section, has a convex form. The form of the supporting surface (4) may be a rounded spherical form, as well as a form with a number of angle forming sides, such as for instance a polygon. Preferably, the yarn lead-through opening (3) is circular. Also a device for detecting the thread breakage on a weaving machine, comprising a number of similar drop pins for stop motion and a weaving machine provided with a similar device are within the scope of this invention.
