The invention concerns a device for controlling forces. It concerns a controlling device comprising a body defining a non rectilinear path for passing a strap ( 18 ) between two support members ( 14 ) arranged on one first side and a support member ( 16 ) arranged on the second side, and provided with a sensor of forces experienced during an impact test, each support member ( 14 ) being separable from the body. An additional support member geometrically interchangeable with a separable support member ( 14 ) is provided with a second force sensor having a measuring range covering the prior working stress of the strap, the controlling device having two different configurations depending on whether a separable member comprises the second force sensor or not. The invention is useful for testing safety belts during impact tests.
