Abstract
A clamp for blocking flow through a flexible hose is formed of a one-piece L-shaped body of rigid material having a short leg formed with a generally circular throughgoing hole through which the hose can pass loosely enough for flow through the tube and a long leg formed with a throughgoing slot narrow enough that when the tube passes through it flow through the tube is blocked. The hole and slot communicate with and open into each other at a corner where the two legs join. The clamp is formed with a generally cylindrical passage forming the circular hole. This passage extends along an axis generally parallel to the long leg of the clamp. The cylindrical passage is formed by a pair of like part-cylindrical surfaces having a common centerline and each in turn formed on a wing-like side part of the clamp.
