A brake sleeve is provided on one of the strap members and a helical spring is located within the brake sleeve and normally frictionally engages an inner surface thereof. The spring has two inwardly angled end portions. An output member is turnably mounted within the sleeve and has a first section extending between the end portions of the spring, and a turnable control member is adjacent the output member and has a second section also extending between the end portions. A torsion spring engages the input and control members and urges the sections thereof into engagement with the respective end portions of the helical spring.
