ABSTRACT:
For an assembly of two bodies wherein one of the bodies has a part-ball portion and the other has a part-ball formed hollow seat of complementary surface, a slot is provided in the body with the hollow portion and the ball formed portion of the other body is mounted into the hollow portion, while a spring washer presses the bodies together when a snap ring having an extension engaging into the slot and being kept in a ring groove is inserted into the hollow portion. The body with the ball formed portion has retaining faces which are engaged by the washer and the washer also has an extension to enter into the slot, whereby the assembly assures, that one of the bodies can pivot relatively to the other body, but that the bodies are prevented from rotational movements relatively to each other.
