摘要： This invention is directed to a device for securing a step of a rope ladder to the rope. The device includes an upper and a lower wedge collar, each of which has a central slot through which the ropes to be secured are threaded. The device further includes a diamond-shaped wedge heart which is inserted in the slot between the ropes such that the ropes are compressed between the sides of the wedge collars and the edges of the wedge heart. The wedge heart also has locking lugs on each edge, each locking lug contacting a surface of the upper and the lower wedge collar to prevent the wedge heart from being pulled through the slot in the wedge collars when pressure is applied to the ropes.
