This device comprises two bars 6a, 6b articulated to the sides of the board 1 in which the blinds 2a, 2b are mounted and can move between a retraction position along the said sides and a transverse position in which they interact together so as to trap the latch 4 of the espagnolette. In the transverse position of the bars, cavities 8 of the latter interact with one another to delimit a housing to receive and trap the latch 4 of the espagnolette. <IMAGE>
