One end of a flexible cable of specified length attached to the end of a shaft and the other end attached to a light-weight and disengageable restraint anchor with a wedge-shaped cross section within a tube. The shaft cannot be removed from the tube, nor can cable be cut, because the anchor is located at a depth in tube greater than the specified length of cable. Anchor is comprised of an inner and an outer piece and operably attached to cable via the inner piece. Outer surface of outer piece essentially conforms to the tube inner diameter. During normal operation (random vibration and impact) the anchor is held in a specific location by a low-force radial force means comprised of a metal snap ring pressing outwards on outer piece. During an undesired removal, the inner piece and outer piece together provide a high-force radial constraint by means of wedge-shaped cross section such that any amount of tension on cable will be insufficient to move anchor from specified location. In order to remove shaft, the wedge-function of the inner and outer pieces are circumvented by reorienting the inner piece or an inner piece lock by electric, gravitational, or magnetic means, preferably by re-orienting the entire shaft and tube assembly in space.
