## Abstract

Tool or adaptor for receiving a tool for securing in a mounting head, including a fork-shaped mounting lug which projects in the direction of displacement and has an enlarged retaining opening starting from a smaller insertion opening.

## Claims

### Claim 1

A tool configured to be secured in a mounting head of a hydraulic pressing apparatus, the mounting head including a groove, the tool being displaceable within the mounting head along the groove in a direction of displacement, said tool comprising a tongue and a lug, both of which extend in the direction of displacement of the tool, the tongue being configured to lay in use in the groove of the mounting head, said lug defining a retaining opening at an end of the tool, said retaining opening configured for securable engagement with the mounting head.

### Claim 2

An adapter for receiving a tool configured to be secured in a mounting head of a hydraulic pressing apparatus, the mounting head including a groove, the adapter being displaceable within the mounting head along the groove in a direction of displacement, said adapter comprising a tongue and a lug, both of which extend in the direction of displacement of the adapter, the tongue being configured to lay in use in the groove of the mounting head, said lug defining a retaining opening at an end of the adapter, said retaining opening configured for securable engagement with the mounting head.

### Claim 3 (depends on 2)

An adapter according to claim 2, wherein said adapter includes a body portion having an exterior surface each of said tongues having an exterior surface, wherein the outer surface of the adapter is flush with the outer surface of each tongue.

### Claim 4

A set of tools configured to be secured in a mounting head of a hydraulic pressing apparatus, said set of tools including a first tool and a second tool, the mounting head including a groove, the first tool being displaceable within the mounting head along the groove in a direction of displacement, said first tool comprising a tongue and a lug, both of which extend in the direction of displacement of the first tool, the tongue being configured to lay in use in the groove of the mounting head, said first tool including a body portion, wherein said tongue extends from said body portion, said tongue having a length measured in the direction of displacement of the first tool and said first tool having a length measured in the direction of displacement of the first tool, wherein the length of the tongue is less than the length of the first tool, wherein the first tool and second tool are configured to be arranged in mirror symmetry in the mounting head.

### Claim 5 (depends on 4)

A set of tools as recited in claim 4, wherein each of said first and second tools include tongue sections which extend beyond a working width of the tool.

### Claim 6

A tool configured to be secured in a mounting head of a hydraulic pressing apparatus, the mounting head including a groove, the tool being displaceable within the mounting head along the groove in a direction of displacement, said tool comprising a tongue and a lug, both of which extend in the direction of displacement of the tool, the tongue being configured to lay in use in the groove of the mounting head, said tool including a body portion, wherein said tongue extends from said body portion, said tongue having a length measured in the direction of displacement of the tool and said tool having a length measured in the direction of displacement of the tool, wherein the length of the tongue is less than the length of the tool, wherein the tool includes a tongue section which extends beyond a working width of the tool.

### Claim 7

A tool configured to be secured in a mounting head of a hydraulic pressing apparatus, the mounting head including a groove, the tool being displaceable within the mounting head along the groove in a direction of displacement, said tool comprising a tongue and a lug, both of which extend in the direction of displacement of the tool, the tongue being configured to lay in use in the groove of the mounting head, said tool including a body portion, wherein said tongue extends from said body portion, said tongue having a length measured in the direction of displacement of the tool and said tool having a length measured in the direction of displacement of the tool, wherein the length of the tongue is less than the length of the tool, wherein an outer surface of a working portion of the tool is flush with an outer surface of the tongue.
