The modular linking system includes a post assembly and a receiver assembly, each of which includes a geared component to permit variously angled, non-rotational engagement therebetween. The receiver assembly includes a locking member that is resiliently moveable to an unlocked position to permit disengagement between the post assembly and the receiver assembly. The locking member includes two arms that are positioned in a slide lockup channel of the post assembly in the locked configuration, where the arms move out of engagement with the slide lockup channel in the unlocked configuration. ## Claims ### Claim 1 A modular locking system comprising: a receiver assembly including: a base;

a cover fitting on one side of the base; a post hole formed in the base, the post hole having a plurality of female teeth defining an exterior surface of the post hole; a space formed between the base and cover; a slide fitting in the space, the slide moveable between a locked position, where a locking surface of the slide interacts to a post assembly to retain the post assembly to the receiver assembly, and an unlocked position, where the locking surface is moved out of interaction with the post assembly; and a lanyard hole formed in an end of the slide, the lanyard hole permitting a user to remotely move the slide into the unlocked position, wherein the locking surface has an arc that interacts, along at least a portion thereof, with the post assembly in the locked position;
