Abstract:
A locking clip 10 for fixing a base to an end of a glass bulb. The locking clip 10 has a body 12 with a first portion 14, a middle portion 16 and an end portion 18. The middle portion 16 is scyphate, i. e. , cup-shaped, and defines a plane, 20 (FIG. 2). The first portion 14 extends away from plane 20 in a given direction by an angle. alpha. , which, in a preferred embodiment, is about 5 degrees. The end portion 18 is connected to the middle portion 16 by a reentrant section 22 and extends away from the plane 20 by an angle. beta. in a direction opposite to the given direction. In a preferred embodiment angle. beta. is preferably about 20 degrees. In a still more preferred embodiment the included angle between first portion 14 and end portion 18 is between 25 and 35 degrees. A centrally located aperture 24 is provided in the reentrant section 22 to aid in the subsequent bending of the end portion 18 at the final welding.
