ABSTRACT:
A connector comprises two parts; namely, a keeper 10 in the form of a substantially flat plate having a slot 12 therein, and a bar 11 which locates in the slot. The keeper has a locking pin 13 which screws into a hole 14 in the keeper and engages the bar. The bar and slot are curved transversely so that pressure by the pin causes a greatly increased frictional grip between the slot and bar than would otherwise be the case if the bar and slot were flat.
The connector has numerous uses such as a straight edged clamp as described in the preferred embodiment or for assembly of a kit of parts where a bar and keeper are incorporated into the respective parts to be joined.
