Abstract: A device for restraining movement without completely prohibiting movement is disclosed. Two coupling devices connected by a extensible material form the physical restraint device. One of the coupling devices may be coupled to a patient while the other may be coupled to a fixed object. The length and extensibility of the extensible material connecting the coupling devices determines the amount of movement allowed between the user and the fixed object. A variety of lengths and strengths of the extensible material may be used and interchanged. Because of the flexibility and extensibility of the material, the physical restraint device may also be used as an exerciser for the person being restrained. A recessed pin locking device is located within each coupling device. Access to each pin locking device is through a hole located in the coupling device. An object such as a pen or a pin must be inserted into the hole in order to release the locking device.
