FIELD: mechanics.
SUBSTANCE: invention relates to connection of pipes. Fitting, provided for interaction with corrugated pipe, contains nut with through channel, provided for installation into it pipes. Pipe is implemented as corrugated and allows sequence of projections and sockets. Multitude of holders are located before nut and allow packing surface, providing for placement it into notches of corrugated pipe. Body with annular groove, formed lengthwise circle around holders, also allows thickening surface. In mentioned body pipe at sealing is pinched between thickening surface of holders and thickening surface of body. Spring, located inside the cavity in holders, is implemented with ability of expulsion of holders inside the groove, when fitting is not sealed.
EFFECT: invention improves reliability of connection and does not require disassembly at design reuse.
