A clip (40) for detecting breakage of window glass which can open and close an opening in a vehicle. The clip (40) holds an end of the window glass (5), and when the window glass (5) breaks, the clip (4) crushes the end of the window glass (5) and detects the breakage of the window glass (5). The clip (40) has a first section (41) and a second section (42) which are formed by bending a steel plate for blade spring and face each other. The window glass (5) is located between the first and second sections (41, 42) which are urged in the direction of approaching each other while being in contact with the window glass (5) at positions shifted from each other. When the window glass (5) breaks, even if it does not break completely leaving a part of the glass remaining in place, the clip can reliably detect the breakage. La présente invention concerne une pince (40) permettant de détecter le bris des glaces s'ouvrant et se fermant dans une ouverture d'automobile. En cas de bris de glace (5), la pince (40) qui serre une extrémité de la glace (5), vient écraser l'extrémité de la glace (5) et détecte le bris de glace (5). La pince (40) est constituée d'une plaque d'acier de ressort à lame pliée qui détermine un premier segment (41) et un second segment (42) qui se retrouvent alors en vis-à-vis. La glace (5) se place entre les deux segments (41, 42) qui ont tendance à se rapprocher l'un de l'autre tout en étant au contact de la glace en des positions décalées l'une par rapport à l'autre. Lorsque la glace (5) se brise, même si elle ne se brise pas complètement et laisse en place un fragment de la glace, la pince peut détecter avec fiabilité le bris de glace.
