A device of integral construction having resilient prongs in a symmetrically concave shell is capable of gripping thin film material of which plastic bags are fabricated. The device can thereby effect closure of such bags. The gripping characteristics of the device can be transiently modified to cause release of a gripped film, thereby permitting re-opening of such bags. The transient modification of the gripping characteristics is achieved by manually applying compressional force to levers associated with the prongs adjacent the base of the shell.
