A connecting device includes a hollow connector body with a front connecting end, a rear insert end, and a threaded intermediate part. A locking sleeve surrounds and holds a tube against the insert end and has a front threaded portion to engage the threaded intermediate part. A resilient press ring is provided around the tube between the insert end and the locking sleeve. The resilient press ring is expandable radially outward so as to facilitate insertion of the rear insert end into the tube, and is contractible by the locking sleeve to tightly press the tube against a surface of the rear insert end. As such, the connecting device can be easily connected to the tube without the need for using a tool to expand the tube.

Un dispositif de raccordement comprend un raccord creux avec un bout de raccordement avant, un bout inséré arrière et une pièce intermédiaire filetée. Un manchon de blocage entoure un tube et le retient contre le bout inséré et a une partie avant filetée pour mise en prise sur la pièce intermédiaire filetée. Une bague à pression élastique entoure le tube entre le bout inséré et le manchon de blocage. La bague à pression élastique peut s'étendre radialement vers l'extérieur de manière à faciliter la mise en place du bout inséré arrière dans le tube et peut être comprimée par le manchon de blocage dans le but de serrer fermement le tube contre une surface du bout inséré arrière. Comme tel, le dispositif de raccordement peut être facilement fixé au tube sans qu'on ait besoin d'utiliser un outil pour dilater le tube.
