Abstract: The invention relates to an apparatus (1) for locking a cord (2), a wire, a tube or any other bendable member into a locking position with a locking portion. The locking portion (3) has at least one open slits shaped receiving cavity (5) defined at one end of the locking portion, the cavities having an opening that is facing away from a portion (7) of the cord that is under tension and the cavity having a width that is less than a diameter of the cord so that the portion (7) that is under tension and a portion (8) of the cord that is received within the receiving cavity are substantially perpendicular to one another.
