ABSTRACT:
A stirrup-shaped support for supporting ear protectors for example has two end parts, between which there is located an intermediate part incorporating an inner section and an outer section. When the end parts are moved away from one another, the inner section is arranged to be subjected to a tensile force while the outer section is arranged to buckle, at the same time, towards the inner section. The rigidity of the outer section is such that the force required to move the end parts away from each other is substantially constant within a predetermined range of distances between the end parts.
