<p>The invention relates to a device (100) for connecting two long parts (101) and (102) end- to- end. The device comprises: a body (20) which extends along an axis x; the body is hollow so as to define an axial cavity (30) having a side wall (33), a first end face (31) and a second end face (32); a first enlarged portion (21) situated at a first end of the body; the first enlarged portion defines a first bottom abutment (23) and a first top abutment (25); a second enlarged portion (22) situated at a second end of the body; the second enlarged portion defines a second bottom abutment (24) and a second top abutment (26); at least one piston (40) comprising a front surface (41) and a stem (42). The piston is housed inside the axial cavity so as to define a chamber (50) able to be pressurized; the stem makes contact against one of the end faces of the axial cavity; and means (52) for introducing/removing a pressurized fluid into/from the chamber.</p> |
