Device for securing an add-on to a support

A device for use in securing an add-on part to a support having an insertion opening with an edge, the device removable with the use of a tool, said device comprising:

• a head part adapted to rest on one of the add-on part and the support, said head part including laterally protruding bearing portions;
• a foot part insertable into the insertion opening and including a back wall, said back wall disposed opposite the edge of the insertion opening when said foot part is inserted in the insertion opening;
• a front wall arrangement resiliently connected to said back wall via a bent-back portion and extending away from said back wall toward said head part, said front wall arrangement further including a tool channel and a free end proximate said head part engageable with the edge of the insertion opening on the side of the insertion opening opposite said head part when said foot part is inserted in the insertion opening, the front wall arrangement further including manipulation structure engageable by the tool when the tool is passed through said tool channel to move said front wall arrangement toward said back wall to release said front wall arrangement from the edge of the insertion opening;
• and
• said manipulation structure further comprising:
• a pair of stop wings formed laterally on said front wall and extending outwardly in a first direction away from said back wall, said stop wings parallel to one another and defining said tool channel therebetween, each said stop wing including a latching step having a contact side and a rear engagement side disposed substantially at a right angle with respect to one another, said contact sides disposed parallel with said front wall and spaced outwardly from said front wall wherein, when said foot part is inserted in the insertion opening, said contact sides are engagable with the edge of the insertion opening with said tool channel defined between said contact sides of said stop wings, and said rear engagement sides are engagable with an edge region of said support that faces away from said head part;
• and
• a guide tongue joined to said free end of, and set at an oblique angle to, said front wall arrangement and extending in a second direction away from said stop wings into the region of said head part and toward said head part at an angle with respect to said back.
