An adaptor bracket for selectively coupling a manifold to a medical device has (i) a tab having a first end and a second end; and (ii) first and second gripping fingers extending from the second end of the tab. The first end of the tab is configured to be coupled to the medical device. The first and second gripping fingers are spaced so as to selectively receive a portion of a manifold within a groove formed between the first and second gripping fingers. The configuration of the bracket enables convenient manipulation of valves and ports on the manifold, such as when the practitioner desires to exchange tubing on the mounted manifold.
