摘要

Improvements introduced in the joining of two articulated parts, of the type in which one of them has a groove through which an arched loop penetrates as a hinge, characterized in that the outer contour contiguous to the groove has been applied to less a bulge that causes a constant friction on the loop where it is housed, while allowing it to be rotated, thanks to the elasticity of the arched loop that embraces it.
