[R] replace last 3 characters of string

I would like to replace the last tree characters of the values of a certain column in a dataframe.

This replacement should only take place if the last three characters correspond to the value "/:/" and they should be replaced with ""(blank)

I cannot perform a simple gsub because the characters /:/ might also be present somewhere else in the string values and then they should not be replaced.  

Could someone help me out on this one?
