• the body is rotated by transmitting the vertical movement in a horizontal circular movement, so that the push button firmly locks the shoelaces, while the jamming is released again by pulling gently upwards.
• the inner body has at least one surface which is beveled with respect to its axis of rotation, the bevel of which extends essentially in the circumferential direction of the body.
• a projection is provided opposite the beveled surface, which slides on the beveled surface when the inner bushing and the outer bushing move relative to one another and thereby rotates the body.
