Abstract

The device (24) comprises a plug (28) which includes a shaft (30) and a head (32). An electrical conductor (26) is located in a longitudinal groove (40) in the shaft and passes through the head and to reduce the chance of damage to the electrical conductor a protective shield (34) is provided which is formed on the head (32) so as to extend upwardly therefrom and be offset laterally with respect to the longitudinal groove (40). When the device is secured to a brake pad (10), the protective shield (34) separates the conductor (26) as it passes upwardly out of the head (32) from the parts of the brake in which heat is generated and abrasion occurs and contributes to avoiding direct contact between the conductor and parts of the brake such as anti-rattle spring (20). The groove (40) is shown as formed from two sides with the conductor passed in in-fashion around the end of the shaft. Two forms of protective shield (34) are illustrated and in Figures 4,5, extension (56) of shield (34) is extended like a hook.
