Abstract: The invention relates to a cock that is used to control the flow of a pressurised fluid, in particular a medical or industrial gas. The inventive cock consists of: a body (1) with an internal fluid distribution circuit (3, 31, 32) comprising an internal fluid passage which fluidically connects a fluid inlet (31) with a fluid outlet (32); means for controlling the fluid flow (4) that can be used to enable or prevent the circulation of fluid in said passage (3); and handling means which are provided with a pivoting lever that is actuated manually by an operator and which co-operate, directly or indirectly, with the fluid flow control means (4). The pin lever (2) (YY) pivots around a pivot point (XX) and can move between at least three stable positions which are angularly staggered in relation to each other. In the rest position, said lever (2) is fixed and solidly connected to the body (1) of the cock and there is zero fluid flow in the internal passage.

Abstract: The invention relates to an air intake for an engine (19) of a motor vehicle. In particular, the present invention concerns a detachable connection between an air collector module (10) and an intake duct module (11) of the air intake. The invention also concerns a method for installing the air intake to the engine (19) of the motor vehicle. A preferred embodiment of the air intake comprises a detachable connection comprising at least one releasable connection arrangement (17) and at least one interlock arrangement (18). The at least one releasable connection arrangement (17) comprises a releasable connector (25) inserted through the air collector module (10) and arranged to secure the air collector module (10) to the intake duct module (11). The at least one interlock arrangement (18) comprises a bracket (31) mounted on one of the air collector module (10) and the intake duct module (11), and an opposing piece (32) mounted on the other of the air collector module (10) and the intake duct module (11).
