A key ring comprising a ring portion having a first end and second end, a rigid loop affixed to the first end, and a catch affixed to the second end for securely engaging and disengaging the rigid loop affixed to the first end is disclosed. The rigid loop and the catch can be typically disposed apart from each other with the ring portion in a relaxed state such that engaging the catch and the rigid loop holds tension between the first end and the second end to secure engagement of the catch and the rigid loop. The catch can be a hook having a tip extending into an enclosed area of the hook. The catch and the rigid loop can be oriented either in or transverse to the plane of the ring portion.
