Abstract
The present invention relates especially to a hydraulic fracturing device which comprises:—a tubular conduit (1);—and, against its external face, a cylindrical sleeve (2) whereof the opposite ends (20) are connected together and hermetically to this external face;—the wall of said tubular conduit (1) comprising at least one opening (10) to have it communicate with the interior of the sleeve (2). This device is remarkable in that said sleeve (2) comprises at least one mechanical weakening zone (21) which is peripheral, sinuous and with closed contour, that is, its opposite ends rejoin, this mechanical weakening zone being capable of breaking under the effect of predetermined pressure (10) known as “burst pressure” applied to the interior of the latter to form in its wall a sinuous opening (3).
