<p>A device for facilitating the initial tensioning of a line comprises two relatively movable parts (35,30) having resilient means (36, 45) acting therebetween, adjustable setting means (38, 46, 42, 43) for providing a preselected initial compression of the resilient means to set the amount of tension load needed applied across the device to initiate relative movement of the parts, and an indicator (39, 19, 44) responsive to that relative movement to indicate when that tension load has been reached. In one form the device functions also as a shock absorber with the resilient means (36, 45) being adapted to provide a progressively increasing resistance to axial extension of the device sufficient to effectively absorb shock loads applied in use. In another form the device functions as a turnbuckle having indicator devices (44) at each end thereof. The turnbuckle can also act as a shock absorber if required for particular applications.</p> |
