Abstract:
Device for mounting blind on an element (57, 58; 57a, 58a) provided with an opening (U; Ua) going from a first space (A) to a second space (B), the said device being designed to be mounted from the said first space by engagement in the said opening in the direction going from the said first space to the said second space, having:a) a first piece (1) having at least one holding lug (4) designed to be inserted through the said opening and a stop means (2) designed to come to bear on a stop surface on the said element in order to axially position the said first piece vis-a-vis the said element, each said holding lug being adapted to flex and having a first projecting part (8) and a second projecting part (9) disposed downstream of the said first projecting part in the direction of engagement,b) a second piece (20) provided with a foot having a first portion (23) having a projecting part (24), a second portion (25) having a projecting part (26) and a breakable part (35) situated between the said first portion and the remainder of the second piece,the said first and second pieces being adapted to cooperate so that, once the first piece has been inserted until it abuts in the said opening, a driving of the said foot with respect to each said holding lug produces, when the said first projecting part of the said first piece and the said projecting part of the said first portion meet, a bending of each said lug around an edge (R; Ra) situated at the end of the lateral wall of the said opening which is on the side of the second space, if the said edge is situated upstream of the said first projecting part (8) of the said first piece in the direction of engagement, or, if the said edge is situated downstream of the said first projecting part (8) of the said first piece in the direction of engagement, produces a breaking of the said breakable part which enables the said projecting part of the said second portion to come up against the said second projecting part of the said first piece.
