Abstract
A joint means for light fittings, such as office lamps, comprising pairs of bars arranged after one another and connected with each other by pairs of joint plates. The plates are pressed against each other and the bars with clamping screws. The bars are connected with the joint plates by means of protuberances on the plates extending into holes in the bars.
