ABSTRACT:
A ball-and-socket joint wherein the socket has a head with a spherical cavity and a one-piece or two-piece shank which extends radially from the spherical external surface of the head. The head is formed with a lateral opening whose diameter is normally less than the diameter of the cavity so that insertion of the ball into and its withdrawal from the cavity through the opening necessitates an enlargement of the opening. This is achieved by forming the external surface of the head with recesses which entail a reduction of the thickness of the corresponding portions of the head and enable the head to expand so that the ball can pass through the opening. That portion of the head which is disposed diametrically opposite the shank and is adjacent to the opening is not formed with recesses. If the shank is made of two sections, such sections can be assembled by snap action and they can confine the end portion of a motion transmitting or motion receiving member. The member is held against axial movement relative to the shank by projections which are provided on the two sections of the shank and extend into circumferentially extending grooves of the end portion.
