This blog post have nice description:

$.fn.extend({
myMethod: function(){...}
});
//jQuery("div").myMethod();

$.extend({
myMethod2: function(){...}
});
//jQuery.myMethod2();

As a general rule, you should extend the jQuery object for functions and the jQuery.fn object for methods. A function, as opposed to a method, is not accessed directly from the DOM.
