A pair of straps used in retaining on a torso-board a person with neck or back injuries. General use requires two sets of these straps to adequately restrain the patient. The two straps in a set attach to opposite corners of the board, utilizing openings through it at those locations. The free ends of the straps then connect to each other to secure the injured person. The attachments of the straps to the board allow changes in the overall effective lengths of the straps. Sections of loops and hooks on the straps achieve these variable attachments to the board. The straps' free ends may also connect together at different positions to produce the required tension to immobilize the individual. One of the straps' free end may include a metal loop with the other possessing sections of engageable hooks and loops. Passing the latter partially through the metal loop and engaging hooks with loops connects the two straps together. The straps' attachments to the board and their variable connection permit the necessary adjustments to accomodate the particular position of the injured person on the board and to remove any possible slack that may occur during their use. The straps need not pass across the back of the board; consequently, the subsequent relocation of the restrained person upon a full length board may proceed with a minimum of deleterious jostling.
