ABSTRACT:
Hermetic connection device comprising a double curve ductile joint (3) and two supports (1,2), the joint (3) being connected between the two supports (1,2) stressed towards each other along axis (8) and defining on one section of their thickness only two parallel surfaces (4,5) at an angle to axis (8), characterized in that in the normally clamped state the geometric characteristics of the supports (1,2) and of the joint (3) are such that contact between the joint (3) and the two supports (1,2) is made on the one hand through each inclined surface (4,5) respectively along a line of contact (9,10) and on the other hand by each extreme end of joint (3) supported against another surface (6,7) of the male support (1) or female support (2) respectively.
