The clamping device comprises: a screw member with a bearing head and a shank equipped with a threaded portion, a retainer (10) comprising a base (21) equipped with a through-hole (20) for the passage of the shank of the screw member, and retaining means supported by the base (21) to lie vertically in line with the through-hole (20), and designed to collaborate with the threaded portion in order axially to immobilize the screw member relative to the retainer (10). The retaining means consist of flexible and elastic tabs (22, 23) arranged such that they converge. Their free ends (221, 231) between them determine a gap (d) smaller than the nominal diameter of the threaded portion (15) so that they automatically engage with the threads of the threaded portion (15) when the shank (12) is inserted axially into the through-hole (20). A burr (29) is arranged at the periphery of the through-hole (20) towards the flexible tabs (22, 23) to form an end stop for the free ends (221, 231) when the shank (12) is axially withdrawn. |
