PCT No. PCT/SE88/00600 Sec. 371 Date Apr. 25, 1990 Sec. 102(e) Date Apr. 25, 1990 PCT Filed Nov. 7, 1988 PCT Pub. No. WO89/04428 PCT Pub. Date May 18, 1989.A device which is externally fitted to a rod-like object has an inner tubular member and an external, rigid tubular member. Each tubular member has a longitudinally extending opening through which the rod-like object can be inserted. The internal tubular member has a conically narrowing outer peripheral surface and an inner surface whose shape approximately corresponds to the peripheral surface of the rod-like object. The external tubular member has a conically shaped inner surface corresponding to the outer surface of the internal tubular member. By axially displacing the inner and outer tubular members, the device will be firmly clamped onto the rod-like object. The device can be used to clamp cloth or fabric to a tubular stand or frame structure. Also suspension devices and connecting devices such as hooks and legs can be attached on the device. |
