Abstract
A handcuff that includes two compression control mechanisms that allow the handcuff to ensure a tight fit, but prevent the handcuff from being over-tightened causing injury and preventing potential liability. The handcuff includes a first half bracelet and a second half bracelet that are pivotally coupled. The first half bracelet includes a base that houses a locking mechanism and the second half bracelet includes a toothed portion that operably engages the locking mechanism. The handcuff includes a first compression control mechanism proximate the first half bracelet and a second compression control mechanism proximate the second half bracelet. The first and second compression control mechanisms engage the locking mechanism and are operable to automatically change the locking mechanism from an active mode to a locked mode to ensure the proper closure of the handcuff, and prevent the handcuff from being over constricted.
