The blade 52 is inserted between the body 1 and the cap 3 and thus maintains the flake 51 and the associated screw. The terminal cover 3 is fixed to the body 1.

Lorsqu'on met en place une lampe 2 dans l'alésage du corps 1, on repousse la lame élastique 42 et on bloque le culot 22 de la lampe dans le corps 1. Les lames conductrices 42 et 52 conduisent le courant électrique entre la lampe 2 et les bornes 4 et 5 respectivement.When a lamp 2 is placed in the bore of the body 1, the elastic blade 42 is pushed back and the base 22 of the lamp is blocked in the body 1. The conductive blades 42 and 52 conduct the electric current between the lamp 2 and terminals 4 and 5 respectively.

Il est bien entendu que l'on peut, sans sortir du cadre de l'invention, imaginer des variantes et des perfectionnements de détail et de même envisager l'emploi de moyens équivalents.It is understood that one can, without departing from the scope of the invention, imagine variants and improvements in detail and even consider the use of equivalent means.
