<p>A guide bushing for guiding a tubular element in a bore of a coupling, the bushing being provided externally with retaining elements for retaining the bushing in the bore, and internally with guide shoes for guiding the tubular element inside the bushing, the retaining elements and the guide shoes being associated with portions of the bushing that are deformable between a first state in which the retaining elements are in an active position anchoring the bushing in the bore and in which the shoes define a section for passing the tubular element, and a second state in which the retaining elements are in inactive position set back from their active position and in which the guide shoes define a section that is smaller than the section for passing the tubular element. The invention also provides a corresponding coupling.</p> |
