Abstract: A mounting bracket having multiple bayonet coupling elements which interengage with the bayonet coupling elements located on the body of an electrical instrument to be attached to a junction box. Additionally and in combination with the bayonet coupling elements, on the bracket and instrument body respectively, are included a pawl and ratchet arrangement for providing fine rotational adjustment while a toothed spring finger attached to the bracket engages a notched annular wall on the instrument body so as to latch and further secure the bracket to the body. It is anticipated that the mounting bracket will have to be attached to any one of several types of junction box thereby necessitating a multidirectional coupling arrangement for properly attaching the subject instrument to the particular junction box encountered.
