A connector is provided including a pair of oppositely positioned branches defining a receptacle structured to receive the post portion. The receptacle is positionable between an open configuration and a closed configuration, wherein the connector is positionable along and about the post portion in the open configuration. The system also includes an elongate support member defining a passage structured to receive and engage a portion of the connector. As the connector is received in the passage, the branches of the connector move toward one another and force the receptacle toward the closed configuration wherein the connector is fixed relative to the post portion.
