104.5° bond angle between each Sulphur and chlorine.

Explanation:

You may want to draw a dot and cross diagram displaying Cl-S-S-Cl
Each Sulphur has 2 lone pairs of electrons and 2 bonding pairs.
This indicates that the structure will be bent.
Following the Valence shell electron repulsion theory each lone pair repels more than bonding pairs by ~2-2.5°
A tetrahedral shape (if there were 4 bonding pairs of electrons) will have 109.5° bond angle so taking into account VSEPR theory the angle between each Sulphur and chlorine in this compound is 104.5°
