The invention relates to a device for connection between two enclosures of a turbomachine, for enabling the circulation of a coolant between said enclosures, via said connection device, said connection device comprising an outer tube having an opening extending along the entire length of said outer tube, and also comprising an inner tube extending inside the outer tube. An ink cartridge 1d for storing a nontransparent ink includes a projection 51 having light transmittance. The strength of the tin solder element to bond the metal shielding can to a circuit board can thus be enhanced so that the metal shielding can can be secured firmly on the circuit board. Tires are supported with their full faces available for inspection by potential buyers. When one of the first fixing member or the second fixing member is rotated, the other is rotated at the same time and to the same degree by virtue of the linking assembly across the third fixing member. This allows rapid design of a study and its questionnaire as well as gathering of respondent data online, quick turnaround times for requested benchmark reports and online delivery thereof.
