Abstract: A faucet fixation system that includes a fastener and a connector having a base and a nut assembly. The base has a longitudinal bore receiving the fastener and a radial bore. The nut assembly is disposed in the radial bore and includes first and second locking members each having threaded and actuating portions disposed on opposite sides of the fastener. In a locking position, at least one locking member is moved relative to the base such that the threaded portions engage the fastener to prohibit relative sliding movement between the connector and the fastener while allowing the connector to rotate along the threads of the fastener. In a non-locking position, at least one locking member is moved relative to the base such that the threaded portions disengage the fastener to allow movement of the connector relative to the fastener.
