The present invention relates to a dropper (1) for use in connecting a conductor (5) and a catenary wire (6) in an overhead electric traction system comprising: a conductor clamp (2) for connecting the dropper (1) to the conductor (5), which comprises a moulded clamp body (7) that snaps onto the conductor (5); a dropper cord (3) connected to the clamp body (7) at the end opposite to that connecting with the conductor (5); and a catenary hook (4) for connecting the dropper cord (3) to the catenary wire (6), wherein the dropper cord (3) is flexible such that the application of a substantially vertically upwards force exerted by the conductor (5) to the conductor end of the dropper cord (3) causes the dropper cord (3) to bend thereby to prevent any upwards movement of the catenary wire (6).

L'invention concerne un cavalier (1) permettant de connecter un conducteur (5) et un fil caténaire (6) dans un système de traction électrique suspendu et comprenant: un serre-câbles à étrier (2) permettant de connecter le cavalier (1) au conducteur (5) et présentant un corps de serre-câbles moulé (7) s'encliquetant sur le conducteur (5); une corde de cavalier (3) connectée au corps du serre-câbles (7) au niveau de l'extrémité opposée à celle connectant le conducteur (5); et un crochet caténaire (4) permettant de connecter la corde du cavalier (3) au fil caténaire (6), la corde du cavalier (3) étant souple de manière que l'application d'une force sensiblement verticale exercée par le conducteur (5) sur l'extrémité du conducteur de la corde du cavalier (3) contraigne la corde (3) de se plier, empêchant ainsi un déplacement vertical quelconque du fil caténaire (6).
