A device for loading bulk products of the type comprising a sleeve adapted to guide bulk materials from an upper hopper towards a lower container, formed by a supple wall provided with reinforcing hoops. The sleeve is retractable by mechanical action. The device has an inner protecting liner disposed at one end, upper or lower, of the sleeve. The liner is concentric, and inside the sleeve, and of diameter corresponding substantially to a small clearance to the inner diameter of the portions folded in accordion manner between two reinforcing hoops. The liner is thus adapted to receive against its outer wall the folded part of the sleeve, placed in an inactive position, resulting in the active part of the sleeve conveying the bulk materials always remaining in a stretched position.
