A portable ice skating rink comprises, in a kit, a plastic sheeting and a number of rigid tubular frame members, adjustable locking supports for the tubular member and protective C-shape members clips to fasten the sheeting to the tubular member. To assemble the kit, the tubular members are connected to each other in a closed loop frame using the adjustable locking supports inserted in facing end thereof and with corners of the loop being formed by connectors. Adjustable locking supports are inserted in between the tubular member to raise the closed loop frame above ground. The sheeting is then laid over ground of the area enclosed by the loop. The protective C-shape members clips are installed thereat to secure the sheeting to the so formed frame with the protective C-shape members running continuously all along the frame such as to protect the sheeting. By inserting levelling block under and into the adjustable locking support a portions of the frame can be raised for levelling purpose.
