This paper proposes to put into perspective the attachment model (Bowlby) and that of psychic envelopes (Anzieu) so as to grasp the contribution of attachment theory to the field of psychopathology. Having laid the foundations of the epistemological debate between these two models, relying on a discussion of the stakes inherent in the psychoaffective development approach, the author refers to current forms of psychopathology, which draw massively on the borderline and narcissistic concepts, in order to discuss the sense and benefits of the "skin-ego" model as an alternative and complement to attachment theory. Beyond altering reference models in psychopathology, this debate and related inputs lead to consider therapeutic applications through a combination of the notion of "caregiving group" - a group version of the attachment figure - and the notion of therapeutic offer as a necessary alternative to the ideology of demand.
