Abstract
The present invention relates to a self-locking union or fitting adapted to be placed between two parts of a circuit to be connected, of the type comprising two end pieces adapted to be fixed to two parts of the circuit to be connected, two half-shells having internal truncated surfaces engaging complementary external truncated surfaces formed on the end pieces, to urge the latter into tight contact when the two half-shells are urged radially towards each other, wherein automatic locking means are disposed on the sides of the two half-shells, each of the half-shells being made fast with one of the end pieces by connecting means allowing a radial displacement of the half-shell with respect to the corresponding end piece, while maintaining the axis of the end piece parallel to that of the half-shell. The invention also relates to a tool particularly adapted to tighten a union or fitting of this type.
