    • The present invention comprises a friction lock attachment device for use in releasably attaching a given member to a support, and this in a manner such that the attaching device need not be disassembled for mounting purposes or manipulated at its rear threaded connection. In the device, a unique ferrule is employed, the reacting surface of which, abutting the shouldered surface of a bolthead, is chamfered or tapered such that only the inner circumferential edge of said surface engages the undersurface of the bolthead used. Bearing friction between the bolthead of the securement bolt and such ferrule surface is thus reduced to an absolute minimum, ensuring that the friction lock attachment device is properly tightened, and this in a manner such that the ferrule, designed for wedging into such given member, will not turn upon such tightening process. Various embodiments of the invention illustrate the ferrule in a number of useful forms.
