A drum brake in a motor vehicle, comprising a parking brake which includes a brake cable connected detachably to a hand brake lever arranged in the drum brake by the brake cable being passed through a retaining member which is connected to the hand brake lever an engaging behind the retaining member by a nipple of larger cross sectional dimensions connected to the corresponding free end of the brake cable is characterized in that the brake cable (6) is passed through a guide tube (7) which is fixed to the anchor plate (1) of the drum brake, is exposed to the outside of the drum brake, and terminates at a distance ahead of the retaining means (8), the inner diameter of the guide tube (7) being somewhat greater than the maximum outer diameter of the nipple (9), in that the retaining member (8) has a guide path (10) for the nipple (9) extending from its front face (11) which faces the guide tube (7) to its rear face (12), and in that rear face ( 12) of the retaining member (8) is provided with a locking member (13) for the nipple (9) positioned there.

A drum brake for a motor vehicle comprising a parking brake including a brake cable, a hand brake lever within the drum brake, retaining means carried by said hand brake lever, and a nipple of larger cross section than said retaining means and carried by the free end of said cable, said cable passing through said retaining means with said nipple engaging behind said retaining means to detachably connect said cable to said hand brake lever, said brake cable passing through a guide tube fixed to an anchor plate of the drum brake and leading at its outer end to the exterior of the drum brake and terminating at its inner end at a distance spaced from said retaining means, the inner diameter of said tube having sufficient clearance with respect to the maximum outer diameter of said nipple as to enable said nipple to pass through said tube when inward force is exerted on said cable, said retaining means comprising a lower end portion of the hand brake lever bent substantially into a U-shape in cross section, the free marginal upper edge of said bent end portion rising upwardly and rearwardly like a ramp from the front face, facing said guide tube, to the rear face of said retaining means, said rear face including locking means for said nipple when the latter is engaged behind said rear face, said inner end of said guide tube being spaced from said ramp-like marginal edge a distance such that said nipple on being advanced through said guide tube engages the front end of said ramp-like marginal edge and runs up on said edge as said nipple continues to be advanced, said ramp-like marginal edge of said bent portion rising by such a degree that in the course of the advance of said nipple on said marginal edge, said brake cable is pressed against the upper inside surface of said guide tube until said nipple drops off the rear end of said marginal edge and behind the rear face of said retaining means.
