A bent wire serves to form a loop for assembly receiving a brush head of a toothbrush, the bent wire also forming a pair of shanks which are received in a handle holding the shanks together to close the loop and return the brush head assembly therein. At least one of the shanks has formations indexable in the handle. Between the end portions of the shanks and the loop, coil springs are formed in the wire to allow mobility of the brush head in all directions perpendicular to the longitudinal axis thereof. |
