Device for linking sleeves joined to drive and drag handles, characterized by the fact that at the end of the races arranged longitudinally of the male element and in the area of plugged, which races are of the same shape and dimensions substantially larger than the protruding elements of the inner wall of the female element, have their ends in dihedral angle, and substantially convex sides determining a bifurcation in the entrance arranged between two immediate races and a central projection so that when facing, the male element carrier of the races along the area of plugged in with the female element in which in its internal wall there are the projections also in longitudinal centering, determines a guide and entrance of one element inside the other and in case the mouth of the races are not in perfect line with the situation of the projections of the female element then the projection between two races of the malechocho lemento, either tipped or by the sides of the formado dihedral angle of said tips and continuing in the advance action of progressive introduction, leads the projections of the female element by the ramps of its walls to the perfect centering reached which the projections of the element female, as they are already inside the races, they finish doing their introduction perfectly without any jamming, (Machine-translation by Google Translate, not legally binding)
