1. A securing apparatus comprising:
- a frame having a pair of plates with each plate having an inwardly facing surface and an outwardly facing surface such that the inwardly facing surfaces of the plates are facing each other, the frame having a first and a second end;
opposed upper and lower wedges having longitudinal tapered edges, the wedges each having an inner face with a longitudinal recess such that when the wedges are disposed in said frame with the inner faces opposed to one another, a longitudinal opening suited for seating a cable is created by the longitudinal recesses,wherein the inner faces of the wedges are substantially perpendicular to the inwardly facing surfaces of the frame;
a cam having a slot suitable for holding the cable, said cam being disposed rotatably between the plates,wherein the inwardly facing surface of each plate is arranged to receive the edges of the wedges such that the wedges may be slidably mounted in the frame with the inner faces opposed to one another, and the edges of the wedges both tapering towards the first end of the frame,wherein by the rotation of the cam, the cam presses against the upper wedge, advancing the upper wedge towards the first end in a longitudinal direction of the cable.

18. A method for securing a cable comprising:
arranging cable in a frame comprising a pair of plates and a first wedge substantially perpendicular to the plates;
holding the first wedge substantially stationary;
inserting second wedge into the frame, such that the first and second wedges squeeze the cable between them;
subsequently rotating a cam to press again the second wedge advancing the second wedge towards a first end and align the second wedge with the first wedge; and
releasing the first and second wedges such that the first and second wedges move in unison in accordance with a tension in the cable.
