Abstract
A quick and leaktight joining device for tubular pipes having two tubular elements to be joined together, a device for locking in the joined condition, and a connection and/or locking telltale which can move between a first, visible, position and a second, concealed, position. Upon joining, one of the tubular elements to be joined and/or a locking device ensure(s) that the telltale is driven from the first, visible, position into the second, concealed, position. The quick and leaktight joining device is used, particularly in the motor industry for joining an engine cooling circuit to the water box of a unit heater or to the joining of a medium-pressure oil circuit of a motor vehicle power-assisted steering circuit.
