A self-locking grip for bags and sheet material is provided having a multiplicity of grit-like points positioned to be brought into firm gripping relation with sheeting or the like draped under tension over these points. Typically, the sheeting is draped over a grit-covered semi-circular surface merging with the grit-covered sidewall of a slot, and held in contact therewith by spongy resilient material fixed to the other side of the slot. This resilient material is readily compressed to receive or to release the edge of the sheet material.
