Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
187 words
A connector for a holder for a lamp or lamp starter comprising a plate having a resilient lug and only two holding lugs formed integrally from the plate by a force-through operation, each holding lug so arranged as to engage a respective projection on said holder when said holder is assembled to the plate, wherein said holding lugs are first and second holding lugs so disposed that said holder can be assembled to the plate only by inserting one projection under the first holding lug and then rotating said holder to an assembled position so as to insert another projection under the second holding lug, said resilient lug being so located as to be biased to a depressed position by said holder while a projection has been inserted only under the first holding lug and said resilient lug being in a locking position when said holder is in said assembled positiOn, said holder being detachable by forcing said resilient lug to its depressed position, rotating said holder about said first holding lug in a reverse direction, and then removing the respective projection from under said first lug.
Claim 2
Dependent Claim
