An assembly for securing at least one tube to a threaded stud includes a pin and a bracket. The pin includes an elongated body, a driving head disposed at one end of the pin, and a coupling head disposed at the other end of the pin. The pin has a bore for receiving the threaded stud. The bracket includes at least one finger and at least one receptacle for receiving and retaining the at least one tube. The pin is insertable into a bore in the bracket to a first position in which the at least one finger of the bracket engages the coupling head and thereby inhibits withdrawal of the pin from the bore in the bracket. The pin is rotatable relative to the bracket using the driving head to thread the pin onto the threaded stud and thereby insert the pin further into the bore in the bracket.
