A current collector shoe traveling along a multipole slide wire with sliding contacts projecting from the sides and spring-mounted in the shoe. Breakouts extend between the lengthwise sides for cassettes insertable from either side, with the sliding contacts being spring-mounted in the cassettes. The cassettes may be made of non-conducting material, and a brass sleeve may be inserted between the cassettes and the sliding contacts. The cassettes may be detachably detented in the collector shoe and have projections on their face side to contact the collector shoe from the outside during installation. Each sliding contact may be engaged by a compression spring and connected rigidly to it, with a Z-shaped sheet metal member having a leg fastened to a free end of the spring and contacting the cassette bottom, with the other leg fastened to the collector shoe on the outside. The compression spring may be a flat strip spring. The terminals for the supply cable cores are at the level of the breakouts and the outside leg of the sheet metal member is fixed by the screw which is part of the terminal. Covers for the cable ducts may be detachably fastened to the collector shoe.
