The system comprises a sheath-casing (8) of variable conformation whose purpose is to receive the fixing component (1). The sheath is arranged so that, in a folded state, it passes through a hole (14) in the material and, beyond the hole and in an unfolded state, it envelops a hardening resin mortar. The sheath-casing (8) can be unfolded in the rest state elastically and, in the sealing position, it can be flared towards the outer wall (2) of the material and abutted against its inner face (16) under the action of a spring (4) connected to a socket (5"), on which the sheath is mounted, and of support devices (7) against the outer face (15) of the outer wall (2). The invention is suitable for attachment to bricks.
