Abstract
A first arched surface (2) having a lower end fenestration (4), protruding from a tubular body (1), intersecting it along a closed oval perimeter (5). A second arched surface (7) placed with body (1) facing first surface (2), with an upper opening (8). Both surfaces (2,7) are related through this same perimeter (5) with identical cross sections. Body (1) and both arched surfaces (2,7) are made of a waterproof material. Surface (7) is elastically deformed along said perimeter (5), having means capable of displacing it between two operative positions. When both surfaces (2,7) have opposed convexities of different sign, they establish a passage (9) communicating inner tubular body (6) through said opening (8) and fenestration (4). When surface (7) acquires a same sign convexity to first surface (2), it settles against the inside of (2) closing passage (9), fenestration 4 and opening (8), with a sealing relationship.
