A device for rapid connection of either a tubular element with a pipe end or a system of tubular elements with a pipe ends.

摘要

Rapid action coupling of an assembly of tubular elements to the end pieces, in particular for the assembly of the pipes or hoses of the circuit of a motor vehicle engine to the tips of the input and output of a heat exchanger (radiator or heater) of the vehicle. & br / & it comprises an elastic ring of the chamber-closing (40) which is adapted to be attached to the tubular elements and cut out to form at least one extendable part (45, 46), said ring (40) comprising on its internal surface of the radial protrusions (52) which rest on said tubular elements in a first position in which the coupling is not assembled, while they are displaced, - for the introduction of the endpieces in the tubular elements -, by the abutment faces associated with the end pieces to be brought into the openings for passage of the tubular elements and of the grooves of the endpieces.
