To have in one’s sleeve is to offer a person’s name for a vacant situation. Dean Swift, when he waited on Harley, had always some name in his sleeve. The phrase arose from the custom of placing pockets in sleeves. These sleeve-pockets were chiefly used for memoranda, and other small articles.

To pin to one’s sleeve, as, “I shanʹt pin my faith to your sleeve,” meaning, “I shall not slavishly believe or follow you.” The allusion is to the practice of knights, in days of chivalry, pinning to their sleeve some token given them by their ladylove. This token was a pledge that he would do or die.
