Fastening device for installing gas or liquid conducting pipes

A fastening device to install a gas or a liquid conducting pipe (10) to a lateral supporting track (13) having a transverse cross section shape of inverted U with inwardly bent ends (15,16) near an opening thereof, comprising:

• a body made of two substantially identical parts (8), each having a hole (1) in an upper part (17) for inserting a bolt, and a bolt (19) for connecting and fastening said substantially identical parts (8) to each other at their upper part, wherein each of said substantially identical parts comprises:
• two parallel side walls (5,6) which are interconnected only in their upper ends thereof to define an interconnection area and having bottom ends free, with a gap (7) between said bottom ends defining a passage for the pipe, and wherein the hole for inserting the bolt is located above the interconnection area (2) such that the bolt is inserted in a parallel direction to said passage;
• and
• near both free bottom ends, a first protrusion (9) in a parallel direction to said passage, and both side walls have in their mid portion a second protrusion (3) in a parallel direction to said passage but in the opposite direction of the first protrusion;
• and
• when the two identical parts (8) are connected to each other by inserting the bolt (19) through the hole (1) of each part, the second protrusions (3) of each identical part are pressed against the corresponding second protrusions of the other identical part, creating mutual two pivot points between the two identical parts, and upon tightening the bolt, the upper parts (17) of the identical parts are brought closer to each other and simultaneously the first protrusions (9) of each identical part are pushed outwardly and upwardly, anchoring the device with the pipe therein to the inwardly bent ends of the lateral track.
