Abstract
The invention concerns a flexible tube comprising a neck whereof the outer surface is provided with irreversible securing means and whereon is mounted a transverse end wall bearing a cylindrical vent. The invention also concerns a rigid end cap provided at least with a sealing shirt and a securing skirt provided with matching securing means, said vent of the flexible tube and said sealing and securing skirt being arranged so as to obtain sealed attachment with longitudinal locking of the rigid end cap on the neck by a simple longitudinal translational movement. Additional means such as those described in FR 2 707 256 or FR 9901530 (elliptical tube) enable by slight rotation after depression, complete rotational locking.
