Irreversibly closable flow control clamp

A flow control clamp for association with a tubing segment, the clamp comprising:

• a) a one-piece, integrally-formed body having a first leg and a second leg, each with a first end and a second end, the first end of the first leg and the first end of the second leg being interconnected, the first and second legs being movable from a first spaced-apart position to a second irreversibly-closed position;
• b) a first aperture in the body located at the interconnection of the first ends of the first and second legs and a second aperture located in the second end of one of the first and second legs, the apertures being configured to permit the clamp to be received on the tubing segment, with the tubing segment passing through the apertures;
• c) the first leg including a first inwardly-projecting contacting member and the second leg including a second inwardly-projecting contacting member opposed thereto, the first and second contacting members being configured to occlude the tubing segment when the first and second legs are in the closed position;
• and
• d) the second end of each of the first and second legs including an engagement member, the engagement members cooperating to maintain the first and second legs in the closed position when the engagement members are brought into contact upon moving the first and second legs to the closed position.
