Claim 12

The headset subassembly defined in claim 6 wherein each retention means at each of the yoke ends is gradually expanded in diameter extending away from the yoke end until reaching a diameter at which its resiliency will allow the support means to be forced over it and then abruptly is decreased in diameter so that once the support means has been forced onto a yoke end it will not slide off.
