PCT No. PCT/SE85/00258 Sec. 371 Date Feb. 21, 1986 Sec. 102(e) Date Feb. 21, 1986 PCT Filed Jun. 19, 1985 PCT Pub. No. WO86/00200 PCT Pub. Date Jan. 16, 1986.A strap tensioning device includes a spring-loaded clamping element which presses a strap extending through the tensioning device against a holding bar using lever action. The device is composed of a minimum number of parts and is made from a monolithic plate of sprung material with cut-outs positioned so that both the holding bar and the clamping element and their mutual connecting parts are formed in one continuous piece from the plate which also forms the framework of the tensioning device. When the clamping element is pressed out of the plane of the frame, the clamping element rotates about a fulcrum and the pinching effect of the device is released so the strap can be released. |
