You can use the options - no_open, to set the field in read mode: do not render as a link.

For example:

<field name="field_name" options="{'no_create': True}"/>

I think it's not possible. For workaround I use functional field with type='char' to only show the value of original field. I make functional field visible for users with limited access rights and invisible for normal users and vice versa visibility for original field.

Hi (i'm new in Odoo) i think i found a workaround. Instead of remove the "clickable" behavior, i redefined the view form for this field. By this way i can filter what the user can see!

In this example, i want to show only  the field "name", and "facture_id" of my model Facture; i dont want people to see the price and other field when they clicked on field facture_ids.

So here is my code : 

<field name="facture_ids" widget="one2many_list"  readonly="1" >

    <tree editable="top">

        <field name="patient"/>

        <field name="facture_id" />

    </tree>

    <form>

        <sheet>

            <field name="name"/>

            <field name="facture_id" />

        </sheet>

    </form>

</field>

<field name="field_m2o" options="{'no_create': True}" />

can delete "create and edit" option and let you search in selection
