The invention relates to a sliding body (25) including an electrical contact shoe (32) that moves on a guide rail (5) along the length thereof, said sliding body being mounted to the front of a guiding assembly in the direction of movement of a vehicle and articulated with said assembly by means of a connecting rod (26) that is designed to rupture upon exceedance of a pre-determined limit. The sliding body (25) includes a device (43) for releasing objects or debris, which is located between the shoe (32) and at least one of the sides of the body, The loss of electrical contact between the shoe and the rail enables a risk of derailment to be detected. The invention is suitable for rail-guided vehicle manufacturers.
