Some embodiments comprise a connector including a rigid housing having a first end and a second end. A second member can be positioned at a second end portion of the housing and be engageable with a second device. The second member can have a body portion having a first body portion, a second body portion, and a flow lumen extending axially through the body portion, an annular covering portion extending in a radial direction away from the body portion, a receiving portion extending away from the covering portion in an axial direction, and at least one protrusion extending radially away from an outside surface of the body portion. In some embodiments, the second member can be supported by the housing such that, in an assembled state, the first body portion is positioned within the housing and such that the annular covering portion and the second body portion are positioned outside the housing.
