A construction for clamping together a first member and a second member. The first member is formed with a bolt hole, and is in contact with the second member which is formed with an elongated slot. The shank portion of a bolt passes through the elongated slot and into the bolt hole to engage with the first member. A block member lying within the elongated slot is formed with a hole through which the shank portion of the bolt passes. The head of the bolt presses the block member into the slot, towards the first member. The side walls of the block member are in contact with the side walls of the slot. At least one of the side walls of the block member or of the slot angles inwards, and the block member is so thick in the direction across the slot that without deformation of the parts the block member cannot be pulled by the bolt so far through the slot towards the first member as to contact the first member. Accordingly by the tightening up of the bolt the block member is wedged into the slot, and thus the relative positions of the first member and the second member are fixed and they are clamped together.
