Abstract
A grommet clip, particularly useful for suspending air conditioning ducts, formed of a flat body having opposite portions snapped together along a fold line with means which penetrate a web on the duct and which define an eyelet to receive hangers for supporting the duct.
Claims2
In combination with a penetratable web, a grommet clip for penetrating said web and providing hanger means therefor comprising:
- (a) a flat body having first and second portions adapted to be brought together along a single fold line thinner than the remainder of the body in one predetermined overlapping position,
- (b) a connecting hole in the first body portion remote from the fold line,
- (c) a pointed snap-in pin projecting from the second body portion remote from the fold line for forcibly penetrating the web and the connecting hole when the body portions are in said overlapping positions to lock the body portions together about the penetrated web,
- (d) finger guard extension means integral with said first body portion and projecting outwardly from that side of the flat body opposite the projecting pin for preventing finger contact with the pointed pin as the body portions are locked together about the penetrated web, and
- (e) first and second eyelet holes located in the respective body portions which are aligned to receive suspension means when the body portions are in said interlocked overlapped position.
