Field terminable cable and plug assembly

A splice module comprising:

• an outer barrel;
• a contact assembly with insulation displacement contacts inserted within the outer barrel;
• first and second wire caps configured to be inserted into the outer barrel on opposite sides and retain a cable and individual conductors of the cable such as to have the conductors engage the insulation displacement contacts of the contact assembly wherein each wire cap has:
• a main housing with an opening and having a series of ramp features and a series of serrations on an interior surface;
• a rotating collar with an opening in line with the opening of the main housing, the rotating collar having a series of follower features configured to be inserted into the opening of the main housing such that when the rotating collar is rotated relative to the main housing, the follower features engage the ramp features to compress the cable inserted with the strain relief system, the rotating collar also having at least one ratcheting tab configured to engage the series of serrations of the main housing such as to provide a ratcheting function between the rotating collar and the outer housing.
