Abstract (en)

This present invention solves the problem of developing a design of an unscrewed detachable connection of a pipe (1) to the bottom of a holder, particularly a screwed lamp-holder, ensuring the required degree of connection reliability. According to this present invention, the detachable connection of the pipe (1) to the holder bottom (2) involves pressing a transversely and outwardly bent circumferential wall end fragment of the pipe (1) in the form of ring sector (5), preferably between a square nut (4) and a bottom edge (6) of an offset, asymmetrical, rectangular-sectioned hole of the holder bottom (2).
