FIELD: process engineering.
SUBSTANCE: device is designed to join two structural elements, for example, two tool parts. First structural element comprises cylindrical locating journal and circular surface extending radially there beyond. Second structural element is equipped with cylindrical mount hole for cylindrical journal to fit therein. Retaining mechanism comprises locking pin fitted in locating journal crosswise hope to displace therein. Besides, there are two locking elements located diametrically opposite each other in second structural element. Every said element abuts by end inner or outer cone on complementary outer or inner cone of locking pin and, at tightening, couples therewith wedge wise. In compliance with this invention, inner and/or outer cone of locking pin and/or one or locking element comprises two coaxial spaced apart contact parts shaped to, in fact, a truncated cone that can interact separately or jointly.
EFFECT: perfected joint.
