Version Control with Git says

The syntax of a refspec is:
[+]source:destination
It consists primarily of a source ref, a colon (:), and a destination ref. The whole format may be prefixed with an optional plus sign (+). If present, the plus sign indicates that the normal fast-forward safety check will not be performed during the transfer.
