Pass parameters from a view to a controller using href in Visual Studio

I need help to pass a parameter from a view to a controller. The problem I have is that when I send the data back to me a null data and not the one I am sending, it is assumed that through the "href:" I should be able to send the variable to the controller. This is my view:

@model List<Model.Cliente>
@{
ViewBag.title = "Cliente";
}
   <h2>Cleintes</h2>

    <table class="table table-striped">
        <thead>
            <tr>
                <th style="width:50px;">Id</th>
                <th style="width:100px;">RUT</th>
                <th>Razsoc</th>
                <th style="width:200px;"></th>
            </tr>
        </thead>
        <tbody>
            @foreach (var a in Model)
            {
            <tr>
                <td>@a.Id_clien<td>
                <td>@a.Rut</td>
                <td>@a.Nombre_clien</td>
                <td class="text-right">
                    <a class="btn btn-default btn-success" href="~/Menu/Ver/@a.Rut" title="Visualizar">
                        <i class="glyphicon glyphicon-eye-open"></i>
                    </a>
                    <a class="btn btn-default" href="~/menu/crud/@a.Rut" title="Editar">
                        <i class="glyphicon glyphicon-pencil"></i>
                    </a>
                </td>
            </tr>
            }
        </tbody>
    </table>

And this is my controller:

using Model;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace Sales.Controllers
{
public class MenuController : Controller
{
    private Cliente cliente = new Cliente();

    public ActionResult Inicio()
    {
        return View(cliente.Listar());
    }

    public ActionResult Ver(string rut)
    {
        return View(cliente.Obtener(rut));
    }
}
}
