Disclosed is a handcuff device for restraining the wrists of a detainee. The device comprises a pair of handcuff members and a link member of unitary construction. Each of the handcuff members have one or more integrally formed mounting posts. The link member is configured to hingedly interconnect the handcuff members about the posts. The unitary construction of the link member, combined with the integrally formed posts of the handcuff members, provide a handcuff device which is strong and durable and which does not require the use of multiple components, such as a pivot pin, and substantially limits the movement of the detainees hands.
