While your questioned was answered I feel compelled to add an answer to a question you didn't ask. Changing control of the equipment doesn't change what it's equipped to. So if your sword was equipped to a creature you control. It changing owners doesn't unequip it. The equipped creature still gets +2/+2 and protection. However, because the sword doesn't grant the sabotage ability but has it itself, should your still equipped creature deal combat damage to a player, even the current controller of the sword. The controller of the sword will gain the 3 life and return a creature to their hand.
