To enable temporary positioning and accurate positioning, and to make sure that a screw head is stably received.
This joint element 1 for mechanically joining structural parts 2 and 3 is formed of two coupling half parts 4 and 5 possible to be engaged with each other. Both the coupling half parts can be fixed to the structural members 2 and 3 by screws 6, and both the coupling half parts have a screw housing part 7 for the screw, and the screw housing part has a screw head receiver 8, and shape of the screw head receiver coincides with a geometry of the screw head 10 over the whole circumference. A support sleeve 9 is continuously provided to the screw head receiver 8 in a direction toward the structural parts 2 and 3, and inside cross section of the support sleeve is expanded in the direction toward the structural parts 2 and 3, and each end surface 11 of the support sleeve is driven into the structural parts 2 and 3 to be joined.
