FIELD: reinforcement bars production.
SUBSTANCE: invention relates to tube fitting for pipes with smooth ends, which is formed from housing parts defining sockets for receiving tubular elements. Sockets are located coaxially with corresponding axes oriented at an angle to each other. Each seat has a channel facing the corresponding axis and having floors with different radii of curvature. Holders are inserted into channels. Holders have teeth and one or more displaced tongue, which interacts with channels to prevent wrong assembly of fitting. Annular seals are inserted into channels located near sockets. Annular seals interact with holders to hold segments spaced from each other by a distance sufficient for installation of tubular elements in seats when fitting is in pre-assembled state. Sockets have holes for visual determination of the presence of holders after assembly.
EFFECT: invention provides indication of correct orientation of holder during connection assembly.
