Claim 0:
1. A tool comprising:
first and second arms, each arm including:
a proximal end comprising a handle portion, and
a distal end, opposite the proximal end, comprising a pair of jaws, each pair of jaws including a top jaw and a bottom jaw, the top jaw including an inner surface configured to engage with a top external surface of a corresponding tubing attachment of a pair of connected tubing attachments, and the bottom jaw including an inner surface, disposed opposite to and facing the inner surface of the top jaw, configured to engage with a bottom external surface of the corresponding tubing attachment of the pair of connected tubing attachments, wherein the inner surface of the top jaw and the inner surface of the bottom jaw are configured to have an invariant spatial relationship relative to each other while a force is applied to the handle portions of the first and second arms;

a pivot mechanism that rotationally couples the arms such that, responsive to the force applied to the handle portions of the arms, the arms are configured to rotate relative to each other around the pivot mechanism in a rotational plane causing the distal ends of the arms pivot away from one another and the proximal ends of the arms pivot towards one another, wherein the pairs of jaws of the first and second arms cooperate to disconnect the pair of connected tubing attachments and slide the pair of disconnected tubing attachments past each other responsive to the force being applied to the handle portions of the arms; and
a spring biasing the arms to rotate to an equilibrium position in which the pairs of jaws are substantially aligned, the inner surface of the top jaw of the first pair of jaws is aligned with the inner surface of the bottom jaw of the second pair of jaws and an outer surface of the top jaw of the first pair of jaws is unaligned with an outer surface of the bottom jaw of the second pair of jaws, wherein the equilibrium position is attained automatically under spring loading once the proximal ends of arms are relieved of loading.
