In a coupling device for a point actuator and/or lock for moving point or crossing parts with a rod transmission, in particular a sliding or locking rod joined by a hinge to the moving part, the moving part or the rod transmission, in particular the switch tongue (2), is rigidly coupled to a strap (4) which engages from behind a bolt (5) coupled to the rod transmission or moving part for transmitting traction forces. At least one elastic compression element is arranged between the rod transmission and the strap (4) or the moving part and can be compressed by the rod transmission when the moving part is put against a rigid rail part, and the strap (4) can be moved out of engagement with the bolt (5).

Dans un dispositif d'accouplement destiné à un actionneur d'aiguille et/ou un organe de fermeture pour parties mobiles d'aiguillage ou de croisement, avec une tringlerie, notamment une tringlerie coulissante ou de blocage reliée de manière articulée avec la partie mobile, cette dernière ou la tringlerie, en particulier la lame d'aiguille (2), est solidarisée avec un étrier (4) venant en prise avec un axe (5) accouplé à la tringlerie ou à la partie mobile pour transmettre des forces de traction. Au moins un élément de compression élastique est disposé entre la tringlerie et l'étrier (4) ou bien la partie mobile, et peut-être comprimé par la tringlerie lorsque la partie mobile est placée contre une partie rigide du rail, et l'étrier (4) peut être désolidarisé de l'axe (5).
