CRAMPING FASTENER DEVICE

摘要

A cramping fastener device for assembling a part (7) to a support portion (18) comprises a fastener clip including a deformable catch element that defines a cramping face (12), said catch element being designed to be pushed through the part and through the support portion and being designed to have a cramping face that is resiliently retractable into the clip. It further comprises a proper-assembly indicator (4) for checking that the clip is properly assembled in the cramping position, said proper-assembly indicator being in the form of a sort of stud that is constrained to retract under the effect of the cramping face retracting so as to be able to start being pushed into the clip.

1. A fastener device for assembling a part (7) to a support portion (18), said fastener device comprising a fastener clip including a head and a deformable catch element that extends under the head in an axial direction (A), and that defines a cramping face (12) spaced apart from the head in said axial direction, said catch element being designed to be pushed through the part and through the support portion in such a manner as to achieve assembly by cramping the part and the support portion between the head and the cramping face of the clip, said catch element being designed in such a manner that said cramping face is retracted resiliently into the clip transversely to said axial direction when the catch element is pushed through the part and through the support portion until the clip is pushed fully through the support portion, the cramping face returning resiliently to outside the clip so as to take up a cramping position for cramping to the support portion whenever the catch element is in said fully pushed-in position, said fastener device being characterized in that it further comprises a proper-assembly indicator (4) for checking that the clip is properly assembled in the cramping position, said proper-assembly indicator being in the form of a sort of stud designed to be pushed axially into the clip, in that said indicator and said clip are designed in such a manner that, when the catch element is pushed through the support portion, the indicator is prevented from penetrating axially into the clip by an abutment (16) on the catch element and, at the same time, the indicator is constrained to retract resiliently and transversely to said axial direction towards the inside of the clip under the effect of the cramping face retracting towards the inside of the clip, it being possible for the indicator to be pushed fully into the clip only when the cramping surface of the catch element comes fully into its cramping position for cramping the support portion from behind, the abutment on the catch element moving out of the way to allow the indicator to pass through in said axial direction.
