Abstract: The present invention concerns a tension indicator for indicating when a strap (2) has reached a predetermined tension level, comprising an audible signal producing member (7) having an abutment surface for engagement with said strap, said audible signal producing member altering its physical configuration in reaction to tension in said strap reaching a predetermined value, wherein the change in physical configuration creates an audible signal.

Abstract: An exercise device (20) comprising a resilient force member (6) which is arranged to be acted on by a user and provide resistance against movement by a user over an operative range. The exercise device (20) further includes a mechanical indicator device (1) which directly provides an audible signal at both first and second points of the operative range of the force member (6) to thereby indicate movement of the force member over a required range. The indicator device (1) comprising an audible signal producing member (9) having bistable first and second physical configurations such that a change in physical configuration creates an audible signal. The audible signal producing member (9) being acted on by the resilient force member (6), in use, to change the physical configuration of the audible signal producing member (9) and produce the audible signal.
