Fluid line safety device

1. A restraining device, comprising:

a resilient member having a generally U-shape with forked ends that curve toward each other;

each forked end having a recess between tines thereof, each recess having a blind end;

a bend in the resilient member being provided with an engagement bump;

the engagement bump and forked ends being aligned such that the engagement bump coincides with a line joining the blind ends, the engagement bump being provided on a U-shaped portion that is opposite and in the middle of the general U-shape of the resilient member;

wherein, when a cylindrical connector assembly tube is placed in the recesses, the engagement bump is urged against a side of the connector assembly.

2. The device of claim 1 , wherein the resilient member is made of a polymer.

3. The restraining device of claim 1 , wherein the engagement bump is on a bowl of the U-shape, and the bump-bearing bowl bends toward the line joining the blind ends forming a W-shape.

4. A restraining member for a connector assembly comprising:

a forked first end having a first recess between tines thereof, the first recess being sized and shaped so as to accept a first tubing connected to one end of the connector assembly;

a closed second end having an opening therein, the second end being sized and shaped so as to accept a second tubing connected to an other end of the connector assembly; and

a bend with an engagement bump arranged between the first and second ends,

wherein the bend is arranged such that, when the first and second ends abut against respective first and second ends of the connector assembly, the first and second ends engaging by threading one into the other and the engagement bump interferingly engaging with a knurled attachment member of one of the first and second ends so as to prevent rotation thereof.

5. The restraining member of claim 4 , wherein the member is made of a polymer.

6. A tubing set comprising:

a restraining member having a U-shaped configuration with a middle bend end risers including:

a forked first end on a first of the risers having a first recess between tines thereof;

a closed second end on a second of the risers having an opening therein; and

the middle bend having an engagement bump arranged on the middle bend between the first and second ends;

a tubing line passing through the opening in the closed second end of the restraining member; and

a connector attached to an end of said tubing line;

the engagement bump being positioned to interfering engage with a first connector attached to the tubing line or a second connector adapted for threadingly connecting with the first connector.

7. The tubing set of claim 6 , wherein the connector is one of a male luer-type connector and a female luer-type connector.

8. The tubing set of claim 6 , wherein the tubing line is a blood tubing line.

9. The tubing set of claim 6 , wherein the engagement bump is on a bowl of the U-shape, and the bump-bearing bowl bends toward a line joining blind ends forming a W-shape.
