Abstract: A detachable key ring includes a durable mounting block with a typical key ring fastened to one end and a reliably securable latching device at the opposite end which is movable between open and closed positions and includes a biasing element for holding the latching device in the closed position. The detachable key ring includes an integral member for selectively maintaining the latching device in the open position and requires a two step process to open the latch. Also, the latch mechanism is unidirectional in function. The detachable key ring may be connected to an interlocking block having a second key ring fastened at one end to form a double-ended detachable key ring.
