Devices and methods are provided for detachably securing cans for use in plumbing, painting, construction, and home improvement. The devices are configured for mounting a structure such as a ladder, scaffold, bench, tool box, saw horse, table, railing, pipe, wood, lumber, metal, or plastic support or other object and further configured for detachably securing cans, such as cans containing PVC glue or primer for a plumber's use. In one device, the securing members have two arms configured to be arranged in an open state for receiving the can with substantially zero insertion force. In that device, the arms have end portions with latching members configured to join together in a first engagement position with the can. In a closed state, the latching members are in a partially overlapping configuration that pulls the arms tightly around the circumference of the can and thereby supplies a compression fit with high pull-apart strength.
