The invention relates to a device for aligning forms, comprising: - a connection piece (9), - two rings, each one integral with one of the forms (3), these rings (6, 7) each defining a centring span (6a, 7a) cooperating with complementary spans of the rod (9a) of the said connection piece (9). It is characterised in that the end of the connection piece which presents the retractable abutment (13) comprises a seat of sufficient size to accommodate within the thickness of the rod (9a) a wedge (19), one of the faces of which constitutes the abutment stop (13). <IMAGE>
