A connector for a pump defining a body having an inlet and an outlet, the connector comprising: a first connector portion having a first end and a second end, wherein the first end of the first connector portion is adapted to be coupled to the outlet of the pump; a second connector portion having a first end and a second end, wherein the first end of the second connector portion is adapted to be coupled to the second end of the first connector portion and the second end of the second connector portion is adapted to be coupled to a hose; the second end of the second connector portion being angularly oriented relative to the first end of the first connector portion; and a connection mechanism coupling the second end of the first connector portion and the first end of the second connector portion; wherein the connection mechanism is movable between a closed position and an open position based on actuation of a resilient portion of the connection mechanism, wherein: the resilient portion of the connection mechanism comprises: a first protrusion coupled to a first annular portion, wherein the first annular portion at least partially encloses the first connector portion; and a second protrusion coupled to a second annular portion, wherein the second annular portion at least partially encloses the second connector portion; the second connector portion remains coupled with the first connector portion in the closed position of the connection mechanism; and the second connector portion is able to be uncoupled with the first connector portion in the open position of the connection mechanism, wherein the first protrusion and the second protrusion are movable relative to each other, and with the first protrusion and the second protrusion moving towards each other the connection mechanism changes from the closed position to the open position, and characterized in that: a stop pin is located, preferably on the resilient portion, between the first protrusion and the second protrusion and formed to interfere with and thus limit the movement of the first protrusion and/or the second protrusion. the connector comprising: a first connector portion having a first end and a second end, wherein the first end of the first connector portion is adapted to be coupled to the outlet of the pump;
