<p>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.</p> |
