Device for tightening and/or loosening accessories and/or parts of e.g. cords, has identical and complementary parts whose translation movement is controlled by internal locking system by action of springs, where cord or ribbon is channeled

摘要

The device has two identical and complementary parts rotated relative to each other such that the parts form a coherent assembly, which includes a main body (1) for equipping with a cavity (2). A vertical solid mass part (4) is equipped with a track system for allowing coupling of the main body and a translation movement of the parts relative to one another. The translation movement is controlled by an internal locking system by an action of springs for an alignment or misalignment of openings (9) in the parts, where a cord or ribbon is channeled.
