Abstract: 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).
