    a ring-shaped holder including an outer thread and an inner curved rim having a curvature radius equal to a radius of said truncated ball for supporting and locking said truncated ball, and means for attaching said ring-shaped holder to said case for providing a passage for said cable to said case through a ring-shaped holder;

    an elongated cylindrical cover having a flanged rim at one end thereof and a hemispherical shape at another end thereof and further including an elongated cutout having a width slightly wider than a width of said arm and extending from a center of said hemispherical shape toward said flanged rim for providing a passage to said arm and for gripping said truncated ball inside a hemispherical portion of said hemispherical shape and for providing said arm with positioning capacity extending through a length of said cutout;

    a locking nut having a thread complementary to said outer thread and an inner shoulder for attaching and locking said elongated cylindrical cover to said ring-shaped holder by engaging said flanged rim with said inner shoulder and tightening said nut onto said outer thread and locking said truncated ball between said inner curved rim and said hemispherical portion, wherein said cylindrical cover can be rotated for positioning said cutout around the axis of said hemispheric shape and said arm can be adjusted to any position within the length of said cutout and wherein said cable passing through said truncated ball and said holder is not obstructed.
