The elaborately designed brake device for a tape rule disclosed herein essentially comprises a housing composed of an upper and a lower housings; a control device having a brake button and a release button, the brake button has an extended supporting arm on its end which being provided with a confining slit; and a brake strap having a spring tongue with a protuberance formed at its end. With this structure, the control device is assembled in the housing with both brake button and release button emerged out of the housing. The brake strap is guided in slide slots formed on the housing such that the protuberance of the spring tongue is mated with the top fringe of the slide slot formed on the lower housing, then by inlaying the top end of brake strap in the confining slit, the bottom end thereof is disposed near to the tape surface, detaining or releasing function of the tape can be performed with the aid of resiliency of the flexed spring tongue.
