Abstract
In an assembly of two parts having flat assembly faces, the upper part has a bore provided with an ovalized orifice and the lower part has an internally-threaded bore, the two bores being coaxial when the parts are in the assembly position. A first connecting member has a threaded end in cooperating relation with the internally-threaded bore and a second connecting member has a portion in contact with one face of the upper part. One member has an ovalized portion which cooperates with the ovalized orifice and has a deformable portion which cooperates with the other member after crimping in order to secure the two members at least against rotational motion.
