How do I connect FixedJoints on collision

I made this script and it some times works but usually it doesn’t.

heres the script
using UnityEngine;
using System.Collections;

public class Pyhsics : MonoBehaviour 
{
	private bool attatched = false; 
	public Rigidbody rigbody;

	void OnCollisionEnter(Collision col) 
	{
		if(attatched == false)
		{
		if(col.collider.gameObject.tag == "Finish")
		{
			if(col.collider.gameObject.GetComponent<FixedJoint>() == null)
			{
				col.gameObject.AddComponent("FixedJoint");
			}
			FixedJoint Join = transform.gameObject.GetComponent<FixedJoint>();
			if(Join.connectedBody == null)
			{
				FixedJoint J = col.gameObject.GetComponent<FixedJoint>();
				J.connectedBody = rigbody; 
				J.breakForce = 8;
				J.breakTorque = 8;
				if (col.relativeVelocity.magnitude > 20)
				audio.Play();
			}
		}
	}
  }
}

I think you wanted both of them to have the same connected body, so you should have done

Join.connectedBody = col.rigidbody;
Join.breakForce = 8;
Join.breakTorque = 8;

To make it set itself, if this isn’t what you wanted, please explain it more so I can tell you what to do.

You also never change attached to true, i don’t know if there is more to the code to do that, but you may want to do that in the enter where all of the connected body is put to make sure that it doesn’t change it’s connected body.
