A triple-lock handcuff (20) of the type having a blade (40) pivotally joined to spaced-apart cheek plates (28, 30) for movement through a locking channel (54) includes several improvements. The lock assembly includes first and second pawl members (84, 86) resiliently urged toward the channel (54) independently of one another by separate springs (102, 104). A key operated extractor block (124) carries a yoke (126) for moving both pawl members (84, 86) simultaneously away from the channel (54) to open the handcuff. The first and second pawl members (84, 86) are spaced-apart within the locking channel (54). An elongate resilient cushion (150) is arranged along the inner edge (46) of the blade (40) so as to assume a first unloaded profile (150A) capable of passing between the cheek plates (28, 30) and, alternately, a second profile (150B) when bearing upon a limb, incapable of passing between the cheek plates (28, 30). A sleeve (152) detachably fastens the cushion (150) to the blade's inner edge (46) while leaving the blade's outer edge (48) free of overlay. When the cushion (150) is loaded, the sleeve (152) locks the cushion (150) on the edge (46) of the blade (40) by urging a pair of opposed feet (160A, B) into grooves (174) formed in the sides (50) of the blade (40).
