ABSTRACT:
a keeper plate for use with strap handcuffs is disclosed. The plate in one embodiment for a single handcuff is generally rectangular, with flattened concave edges disposed on its longer sides and strap-receiving channels extending through its shorter sides. The flattened concave edges generally conform to the shape of the palm side of a human wrist and enable a strap handcuff to be tightened securely with minimized danger of cutting off circulation. In another embodiment for a pair of handcuffs, the plate is elongated and has a channel for receiving one strap handcuff disposed spaced apart from a flattened concave edge at each end. This enables securing of limbs without bringing them closely together. Holes may be provided in the plates to enable tying to other straps or other objects.
