An improved carabiner configured to provide an enlarged gate opening for access and to permit smoother entry and release of ropes or other accessory devices to or from the carabiner, the carabiner comprising a C-shaped member with an articulated gate member extending across the opening of the C-shaped member and configured such that the articulated gate member may open beyond the normal interference with the back portion of the C-shaped member. Preferably, an end portion of the C-shaped member includes a slot and a bar extending transversely across the slot, with a complementary narrowed end portion on the movable gate member adapted to fit within the slot and including a notch configured to fit around the bar when in the slot to form a latch arrangement. The narrowed and notched portion on the end of the movable gate member enables the gate member to be further displaced, either into an opening defined in the back wall of the C-shaped member, or, in conjunction with an angled pivot member, offset to the side from the back portion of the C-shaped member. Also, by uniquely providing the slot and bat latch structure in the end of the C-shaped member, a smooth, noninterfering surface …
