Some assemblies can include a male cap and a female cap, each of which can be used to cover separated medical connectors. In certain arrangements, a male cap can include a movable carriage that transitions from a retracted position when an assembly with which the male cap is associated is in a closed state to an extended position when the assembly is in an open state.
