Spring fastener

An assembly of a first part comprising a body panel and a fastener, the fastener comprising

• a bottom portion;
• a first side having an inward facing gusset connected to the bottom portion;
• a second side having an inward facing gusset connected to the bottom portion, thereby forming a U-shaped structure with the first side;
• wherein the first side inward facing gusset engages the second side inward facing gusset when at rest;
• a first engagement spring connected to the bottom portion;
• a second engagement spring connected to the bottom portion;
• and
• each of the first and second engagement springs comprising a peak and a free end;
• at least one engagement spring having two spring sides and a side-cut on each spring side, the side-cuts being across each other, thus forming a side-cut section aligned to be substantially parallel to the peak, each side-cut including an upper edge and a lower edge.

A vehicle comprising parts connected with a fastener, the fastener comprising:

• a bottom portion;
• a first side having an inward facing gusset connected to the bottom portion;
• a second side having an inward facing gusset connected to the bottom portion, thereby forming a U-shaped structure with the first side;
• wherein the first side inward facing gusset engages the second side inward facing gusset when at rest;
• a first engagement spring connected to the bottom portion;
• a second engagement spring connected to the bottom portion;
• each of the first and second engagement springs comprising a peak and a free end;
• at least one of said engagement spring having two spring sides and a side-cut on each spring side, the side-cuts being across each other, thus forming a side-cut section aligned to be substantially parallel to the peak, each side-cut including an upper edge and a lower edge.
