A system and method for an amusement construction system offering simple, safe, and efficient features and solutions unavailable in any other amusement construction system. An anchor body supports one or more extensions, each extension may include one or more semi-flexible loops. The loops are semi-flexible in that they may be deformed to pass through another semi-flexible loop while springingly returning to the undeformed state which is rigid enough to maintain a desired level of coupling. A decoupling strength is related to how easily the semi-flexible loops deform sufficiently to pass through a loop to which it is coupled.
