Each wedge is made of a soft metal, such as mild steel, which is deformable by a cable during use. Each wedge has holes 8 wherein pins 9 may be inserted to limit entry of the wedge into the passage whereby the cable tension is adjustable. A number of the housings may be secured to a plate having openings aligned with the passages. As shown in Fig. 3, each housing 11 is secured to an apertured flange, and a plurality of the flanges are secured together. One end of each housing has a lip to attach a flexible sheath 21 which is secured to a junction member 22 connected to a common sheath 23. As shown in Figs. 5, 6, the housing 28 has two pairs of passages, the side walls of one pair diverging in the opposite direction from those of the other pair to couple four pairs of cables together. The two outer passages are parallel to the inclined outer walls of the housing and the two inner passages are parallel to the axis of the housing. The cables 25 are secured to an anchoring device 26 and the cables 27 extend from a cable sheath 29.
