ABSTRACT:
The invention relates to a one-piece plastics fastener for positively fastening an element to a support, permitting removal of such element while the fastener is self-retained thereon.
The subject fastener of this invention is so devised as to enable it if necessary to be mounted on the element to be fastened prior to mounting of the two together on the support, which is important in the event of assembly-line operations.
A one-piece self-retained and reusable fastener according to this invention is characterized essentially in that it is constituted of two parts which are joined together before use by connecting means breakable at will, said first part being adapted, after the second part has been mounted by elastic deformation into at least the appropriate opening formed in the element to be fastened and, if necessary, into the appropriate opening formed in the supporting element, to penetrate, after said connecting tips have been broken, into the second part whereby to cause, on the one hand, its own sliding maintenance within the second part and positive and final locking of said second part in the opening formed in the element to be fastened and, on the other, when it is pushed home into the second part, locking thereof in the opening formed in the supporting element.
As is known, one-piece plastics fasteners are generally used to fasten various elements to a support. As a rule, such fasteners serve to receive a secondary fastening means such as a screw, and the two together secure such various elements to the support. Removal is effected by separating the secondary fastening means from the plastics fastener, whence the risk of losing one or the other of these two fastening elements when reassembling.
