Patent AT-E401524-T1: [Translated] AUTOMATICALLY CLOSING DEVICE FOR FASTENING AN ELEMENT TO A FIXED SUPPORT

The invention relates to a device (10) for fixing an element to a fixed support, comprising an automatically-closing holding collet (11). The collet (11) comprises a main cradle (15) and secondary cradles (16, 17) forming the jaws thereof. The secondary cradles (16, 17) form a central support zone (20), co-operating with the element to be fixed, in order to actuate the automatic closure of said secondary cradles (16, 17). The collet (11) also includes an actuation pin (34) and a dowel (28), comprising two parallel deformable posts (32a, 32b) which define a slot (33). The pin (34) co-operates with the dowel (28) in order to lock the collet (11) in a housing in the fixed support, comprising the insertion of the actuation pin (34) in the slot (33) and the radial expansion of the posts (32a, 32b) during the automatic closure of the secondary cradles (16, 17).
