A hose coupling (2) which has an integrally moulded lip (1) which has an innermost surface defining a frusto-conical shape (5) and a portion of reduced thickness (10) to provide for pivoting freedom of the lip to effect both a grip and seal of a hose that can be inserted therethrough. Tails (11) are segmented allowing for expansion or contraction as necessary of the lip (1) but providing a limit to the pivotal freedom of such lip. |
