Abstract: A linking assembly for reliably and securely interconnecting thin-walled welded tubes in order to assemble a floor lamp pole includes a hollow plug member which fits securely into one hollow tube member and mates with a socket securely fitted into an adjacent tube member. Each of the plug and the socket are provided with several slots therethrough, which provide arc flats, which are bendable inwardly to provide additional elasticity and assist insertion into a corresponding tube. An internal strengthening circumferential flange is provide to increase rigidity, and longitudinal channels in the socket and plug prevent rotation relative to the tubes of the lamp pole.

Abstract: A connecting assembly for fixing the tubular stem/stud of a portable lamp to the base of the same comprising a tube having a butting shoulder to abut upon the upper end of a top hole in the base of a portable lamp, and folding tabs at the lower end of the tube which are folded outwardly to fix the tube tight to the base. As the tube is expanded during a folding procedure, a tight fit is realized. The top hole in the base may include one or two recessed tubular portions to facilitate assembly and ensure rigidity of the assembly.
