How to have a 3D anchor point that limits how far you can go?

I created a grapple script where if you press a button the hook launches however I want to know if there is a possible way for that when the hook does attach to an object, it creates an anchor point so that the player cant move a certain distance away from it without it pulling the player back.

     public KeyCode leftHook;
     public KeyCode rightHook;
 
     public KeyCode leftGas;
     public KeyCode rightGas;
 
     public GameObject hookLeft;
     public GameObject hookLeftHolder;
 
     public GameObject hookRight;
     public GameObject hookRightHolder;
 
     public float hookTravelSpeed;
     public float playerTravelSpeed;
 
     public float maxDistance;
     private float currentDistance;
 
     public bool firedLeft;
     public bool hookedLeft;
 
     public bool firedRight;
     public bool hookedRight;
     // Use this for initialization
     void Start () {
         
     }
     
     // Update is called once per frame
     void Update () {
      
             if (Input.GetKeyDown(leftHook) && !firedLeft)
             {
                 firedLeft = true;
             }
             if (Input.GetKeyDown(rightHook) && !firedRight)
             {
                 firedRight = true;
             }
         
 
         if (firedLeft)
         {
             hookLeft.transform.Translate(Vector3.forward * Time.deltaTime * hookTravelSpeed);
             currentDistance = Vector3.Distance(transform.position, hookLeft.transform.position);
 
             if(currentDistance >= maxDistance)
             {
                 ReturnHookLeft();
             }
         }
         if (firedRight)
         {
             hookRight.transform.Translate(Vector3.forward * Time.deltaTime * hookTravelSpeed);
             currentDistance = Vector3.Distance(transform.position, hookRight.transform.position);
             if (currentDistance >= maxDistance)
             {
                 ReturnHookRight();
             }
         }
         if (hookedLeft)
         {
             // Creates the anchor point
         }
         if (hookedRight)
         {
             // Creates the anchor point
         }
 
 
     }
     void ReturnHookLeft()
     {
         hookLeft.transform.position = hookLeftHolder.transform.position;
         firedLeft = false;
         hookedLeft = false;
     }
     void ReturnHookRight()
     {
         hookRight.transform.position = hookRightHolder.transform.position;
         firedRight = false;
         hookedRight = false;
     }
