Abstract
A site for access to the inside of a channel, the site having a receptacle communicating with the inside of the channel in order to hold a plug made of an elastic material and intended to form a leak-tight barrier between the inside of the channel and the outside of the channel. The plug has a thickness on a longitudinal axis, an interior surface oriented towards the inside of the channel, and an outer surface facing away from the inner surface. Further, the plug has an upper part having an outer surface of the plug as its upper limit and having a cross section corresponding substantially to that of the receptacle so as to cooperate exactly with the receptacle. The plug also has a lower part having the inner surface of the plug as its lower limit and having a cross section increasing in two opposite directions perpendicular to the longitudinal axis of the plug.
