FIELD: machine building.

SUBSTANCE: invention relates to a fastening device for connecting two parts together. Device comprises a female element with a cavity extending in the axial direction and having a tubular inner surface, a male element in the form of a rod extending axially into the cavity, and a retention means made in the form of a U-shaped bracket, which enters the socket of the female element, passing transversely through the axial cavity, clamping the male element and locking it in the axial position in the cavity of the female element. Retention means is equipped with means for preventing the U-shaped bracket from twisting in the event of pulling the male element out of the female element, which contain the first rib on the U branches, protruding in the axial direction from the U branches into the cavity and coming into the stop position into the tubular inner surface of the cavity, preventing the U branches from twisting during this pulling-out.
