The baulking element is arranged with respect to the second fastener and the second seat such that fastening the second fastener against the second seat causes the baulking element to cant from a non-baulking position into a baulking position in which the baulking element prevents further fastening of the first fastener. ## Claims ### Claim 1 An assembly comprising: a first seat; a second seat; a first fastener which fastens against the first seat; a second fastener which fastens against the second seat; and a baulking element disposed between the second fastener and the second seat, wherein the baulking element is arranged with respect to the second fastener and the second seat such that fastening the second fastener against the second seat causes the baulking element to cant from a non-baulking position into a baulking position in which the baulking element prevents engagement of a fastening tool with the first fastener. ### Claim 2 (depends on 1) The assembly according to claim 1, wherein the baulking element obstructs access to the first fastener when the first fastener is fastened against the first seat and the baulking element is in the baulking position. ### Claim 3 (depends on 1) The assembly according to claim 1, wherein the baulking element allows access to the first fastener when the first fastener is fastened against the first seat and the baulking element is in the non-baulking position. ### Claim 4 (depends on 1) The assembly according to claim 1, wherein the baulking element and the second seat have respective curved surfaces which cooperate to guide the baulking element from the non-baulking position to the baulking position. ### Claim 5 (depends on 1) The assembly according to claim 1, wherein the baulking element and the second fastener have respective flat surfaces which cooperate to cant the baulking element from the non-baulking position to the baulking position when the second fastener is fastened against the second seat. ### Claim 6 (depends on 1) The assembly according to claim 1, wherein the baulking element is biased towards the non-baulking position. ### Claim 7 (depends on 6) The assembly according to claim 6, wherein the baulking element comprises a protrusion which extends laterally with respect to a direction in which the second fastener is fastened against the second seat thereby providing an imbalance of the baulking element about the second seat so as to cause the baulking element to tilt under gravity into the non-baulking position when the assembly is in an upright position and the second fastener is released. ### Claim 8 (depends on 1) The assembly according to claim 1, wherein the first fastener has a profiled portion having a non-circular profile for engagement by a fastening tool, and the baulking element obstructs access of the fastening tool to the profiled portion when in the baulking position. ### Claim 9 (depends on 1) The assembly according to claim 1, wherein the second fastener comprises a nut threaded on a bolt, and the baulking element comprises a spacer element having a bore through which the bolt extends. ### Claim 10 (depends on 9) The assembly according to claim 9, wherein the bore diverges in a direction towards the second seat such that the spacer element can be canted between the baulking position and the non-baulking position. ### Claim 11 (depends on 1) A clamp comprising: pivotally connected first and second jaws, and the fastening assembly according to claim 1, wherein the first and second fasteners are disposed at the free ends of the pivotally connected first and second jaws for clamping the pivotally connected first and second jaws together. ### Claim 12 An assembly comprising: a first seat; a second seat; a first fastener which fastens against the first seat; a second fastener which fastens against the second seat; and a baulking element disposed between the second fastener and the second seat, wherein each of the first and second fasteners have a profiled portion which can be engaged by a tool for tightening the fastener, and the baulking element is arranged with respect to the second fastener and the second seat such that fastening the second fastener against the second seat causes the baulking element to cant relative to the first fastener from a non-baulking position into a baulking position in which the baulking element obstructs access to the profiled portion of the first fastener by the tool for tightening the fastener. ### Claim 13 An assembly comprising: a first substantially concave shaped seat; a second substantially concave shaped seat; a first fastener which fastens against the first substantially concave shaped seat; a second fastener which fastens against the second substantially concave shaped seat; and a baulking element disposed between the second fastener and the second substantially concave shaped seat, wherein the baulking element: i) has a shape that is substantially complimentary to the second substantially concave shaped seat, and ii) upon fastening of the second fastener, is configured to cant into a baulking position in which the baulking element: i) engages with the first fastener, and ii) prevents engagement of a fastening tool the first fastener.
