Abstract

The invention relate to fixing a plug in the end of a bar, the assembly being used for production of cylindrical hollow blanks which will be later rolled. The device comprises a plug including at its rear end a shank which can be introduced into an axial socket provided at one end of the bar. A locking means can be introduced transversely through a hole in the wall of the bar and engage its end within a groove realized around the shank. A retaining means holds the locking means in position. The device is used for rapid mounting and dismantling the plug and bar assembly.
