An intermediate support for a weaving heddle frame in which the support carries both tensile and compressive forces between the upper and lower frame staves. The support can be disengaged from the lower frame stave simply by loosening a fastener at the top of the support and can then be swung upwardly to clear the space between the two frame staves. The support comprises a flexible cable, surrounded by at least three rigid hollow segments. In use, the lower end of the cable is inserted into a slot in the lower frame stave and the upper end of the cable into a slot in the upper frame stave. The two slots are aligned vertically. The cable is tensioned by the use of a plug which is connected to the upper end of the cable and which threadedly engages nuts attached to the upper frame stave. When tension is applied to the cable, the lower stave is urged upward into contact with the lower end of the rigid hollow member and the upper stave is urged downward into contact with the upper end of the rigid hollow member. Tension forces in the cable and the compressive forces in the rigid hollow member hold the upper and lower staves in a predetermined parallel relationship. When the cable is loosened sufficiently. The segments forming the rigid hollow member separate, allowing the support to be bent out of the way.
