RACCORD POUR TUYAUX

摘要

A quick-action pipe or hose coupling made of a plastics material comprising a male and female member for attachment to respective free ends of first and second pipes to be coupled together, the female member being shaped to receive said male member and having at least two locking members thereon, each locking member having first and second parts for cooperation with said male member to grip and retain it in the female member, said first part being shaped to cooperate with the male member so that said pipes are drawn together when the locking member is moved from a release position to a clamping position and said second part having an abutment surface which abuts against a corresponding abutment surface on the male member when the lever is in its clamping position to prevent axial separation of the pipes. Conveniently each locking member is an over-center lever which is pivotally attached to the female member, the male member being provided with an annular recess and V-shaped groove with which the correspondingly shaped first and second parts on the over-center levers cooperate. The coupling can have a pair of diametrically opposed levers as illustrated but more levers can be provided depending on the use of the coupling.
