connecting cables

Hi

I want to connect cable ends, when do so i can't manage to freeze the positions of both cable and target.
I used the .FreezeALL constrains and it activated it but that does not much.

any Inputs?

this is my code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class connectors : MonoBehaviour
6. {
7.  
8.     #region Class members
9.     [SerializeField] private bool snapped;
10.     public RigidbodyConstraints constraints { get; private set; }
11.     #endregion
12.  
13.     private void OnTriggerEnter(Collider other)
14.     {
15.         Debug.Log("hit");
16.  
17.  
18.         if (other.tag.Equals("Cable_end") || other.tag.Equals("Cable_start"))
19.         {
20.             snapped = true;
21.  
22.             var cable = GetComponent<Joint>();
23.             cable.connectedBody = other.GetComponent<Rigidbody>();
24.  
25.             cable.connectedBody.constraints = RigidbodyConstraints.FreezeAll;
26.           // cable.connectedBody.drag = 0;
27.  
28.         }
29.  
30.         if (snapped)
31.         {
32.             Debug.Log("Kabel snapped: " + other.name);
33.         }
34.     }
35.    
36.  
37. }
