The present invention relates to a connecting pipe (8), providing the refrigerant fluid circulating in the cooling cycle in the compressors (1) to be delivered to the suction muffler (5) or the cylinder head (4) after it enters the compressor (1), attenuating both the radial and axial movements of the compressor (1) motor, preventing the transfer of motor vibrations to the shell (2) and providing for balancing of pressure within the inner volume of the shell (2). The connecting pipe (8) is produced of a material hard enough to withstand the high temperature environment within the shell (2) without failure.
