Tubular connection unit, has locking spacer comprising abutment portion that is arranged against leg, and exerting support by abutment portion against leg to hold fastening units when bearing surface is subjected to pressurize fluid

摘要

The connection unit (1) has a tubular base plate (5) comprising a fastening unit (14) i.e. groove (15), and a tubular body (3) comprising another fastening unit (42) i.e. pin (43), which co-acts with the former fastening unit so as to block an axial relative movement of the body in the plate. A locking spacer (7) is movable in relation to the body and/or the plate. The spacer has an abutment portion arranged against a deformable leg (33), and exerts a support by the abutment portion against the leg to hold the fastening units when a bearing surface (64) is subjected to pressurize fluid.
