A holder including a base for platform mounting. The base includes a clamp for securing a tube wringing device thereon. One handle of the tube wringing device is adjustably confined by a latch on the base which exerts pressure on the handle and a roller thereon urging the roller into engagement with a remaining roller and a tube therebetween. The latch may be resiliently mounted so as to yield during roller operation.
